I had fairly good results (not amazing but they did help) using the sea bands (acupressure) which you can get at most drugstores. Since my pregnancies, I have become more familiar with natural cures and wish I had had a few more tricks up my sleeve back then! Never-the-less, hopefully these can be helpful to you!
Homeopathy is gentle and safe during pregnancy but you need to try to find the right remedy that matches the most of your symptoms. Here is an article that might be helpful in finding a remedy that would help your nausea:
"Nausea during pregnancy can be miserable. At at time when many changes are occurring (enough to adapt to already), it is often very discouraging. Some women only feel ill or queasy in the morning, but for some it lasts all day and is even troublesome at night. Discomfort usually eases off by the third or fourth month, but not always. Homeopathic remedies can be very helpful to a woman with morning sickness and are safe to take during pregnancy.
For dosage information, please read the information at the end of this section. See also “Using Homeopathy With Professional Guidance” in What Is Homeopathy?
Asarum: This remedy is indicated when a woman feels very ill, with constant nausea and retching. She is extremely sensitive to everything—especially noise, which can aggravate the nauseous feelings. She feels best when lying down and resting. Cool drinks or food may help, but it is hard for her to even think of eating.
Colchicum: Horrible nausea that is worse from the sight and smell of food (especially eggs or fish) often indicates this remedy. The woman retches and vomits, and has a sore and bloated feeling in the abdomen. She has trouble eating anything — although she often craves things, when she tries to eat them they make her sick. She is likely to feel ill from many smells that others don’t even notice.
Ipecacuanha: This remedy is indicated for intense and constant nausea that is felt all day (not only in the morning) with retching, belching, and excessive salivation. The woman may feel worse from lying down, but also worse from motion. Even after the woman vomits, she remains nauseous.
Kreosotum: When this remedy is indicated, the woman may salivate so much that she constantly swallows it, becoming nauseous. She may also vomit up food that looks undigested, several hours after eating.
Lacticum acidum: This remedy is indicated for “classic morning sickness”: nausea worse immediately on waking in the morning and on opening the eyes. The woman may salivate a lot and have burning stomach pain. She usually has a decent appetite and feels better after eating.
Nux vomica: Nausea, especially in the morning and after eating, may respond to this remedy—especially if the woman is irritable, impatient, and chilly. She may retch a lot and have the urge to vomit, often without success. Her stomach feels sensitive and crampy, and she may be constipated.
Pulsatilla: This remedy can be helpful if nausea is worse in the afternoon and evening (often in the morning, as well). The woman is not very thirsty, although she may feel better from drinking something cool. She can crave many different foods, but feels sick from many things (including foods she craves). Creamy foods or desserts may be appealing, but can cause discomfort and burping or bring on vomiting. A woman who needs this remedy usually is affectionate, insecure, and weepy—wanting a lot of attention and comforting.
Sepia: Gnawing, intermittent nausea with an empty feeling in the stomach suggests a need for this remedy. It is especially indicated for a woman who is feeling irritable, sad, worn out, and indifferent to her family. She feels worst in the morning before she eats, but is not improved by eating and may vomit afterward. Nausea can be worse when she is lying on her side. Odors of any kind may aggravate the symptoms. Food often tastes too salty. She may lose her taste for many foods, but may still crave vinegar and sour things.
Tabacum: This remedy can be helpful to a woman who feels a ghastly nausea with a sinking feeling in the pit of her stomach. She looks extremely pale, feels very cold and faint, and needs to lie very still and keep her eyes closed. If she moves at all, she may vomit violently—or break out in cold sweat and feel terrible.
Homeopathy Dosage Directions
Select the remedy that most closely matches the symptoms. In conditions where self-treatment is appropriate, unless otherwise directed by a physician, a lower potency (6X, 6C, 12X, 12C, 30X, or 30C) should be used. In addition, instructions for use are usually printed on the label.
Many homeopathic physicians suggest that remedies be used as follows: Take one dose and wait for a response. If improvement is seen, continue to wait and let the remedy work. If improvement lags significantly or has clearly stopped, another dose may be taken. The frequency of dosage varies with the condition and the individual. Sometimes a dose may be required several times an hour; other times a dose may be indicated several times a day; and in some situations, one dose per day (or less) can be sufficient.
If no response is seen within a reasonable amount of time, select a different remedy."

Most of these remedies can be found at your local health food store or New Season's or Whole Foods if you have one nearby (or online of course).
Otherwise, I have had many clients tell me that wearing a hazelwood necklace helps reduce their nausea (the wood has the natural property of absorbing acidity) and a lot of times, morning sickness is exasperated by a lot of acidity in the stomach (which is why eating crackers can sometimes help as it helps to absorb some of the acidity so it's not upseting your stomach so much). The necklaces are also very helpful at reducing heartburn and acid reflux that is very typical especially later in the pregnancy. They are available at: www.hazelaid.com
Hope you feel better soon. Morning sickness is no fun at all!
