I had the same thing, even ended up in the hospital with my first pregnancy. I found things that helped, but nothing that really worked. I tried ginger tea, sucking on lemons, eating small doses of protein, wearing the seasickness bracelets, prayer . . .
The constant oh-my-God-did-I-just-get-off-a-whirling-carnival-ride-and-could-I-die-now-please nausa lasted about 4 months. I continued to throw up at least once a day until I was 7.5 months pregnant with my first child. With my second son, I vomited right up until I went into labor -- and even during labor some.
For my third child, I only experienced a little nausea as the plane took off from JFK on it's way to Bucharest to bring home our adopted son.
During my first pregnancy, I swore that I would never ever get pregnant again -- then Chris was born and I realized just how wonderful it was to have a baby. So when he was two, we got pregnant again (after all, each pregnancy is different, right?)
During my second pregnancy, I went one better. I swore to God that not only would I never get pregnant again -- I'd never had another baby. I was so sick of being sick . . .
I was oh so smug in my decision to never be pregnant and never bring home another baby. I thought I was done with two. And I knew adoption was never going to happen: babies are too hard to find in America. And who in their right minds would spend 15-25K to adopt something that might be damaged when I could make a perfect one from scratch? Two boys, that was it.
Then my husband and I went to a marriage enrichment conference. Someone casually mentioned adopting internationally and suddenly, the another-kid-hunger swallowed us again. Eighteen months later, we brought home our son.
Yes, we spent 17K.
Yes, he turned out to have chronic issues (autism, MR, speech problems, turret's, adhd . . .)
Yes, we could have made one from scratch.
No, I didn't get pregnant again.
No, I didn't bring home another baby (he was 3.5 yrs)
Yes, I love him just the same and would do it all over again (pregnancy or adoption) if I felt that my family was missing a member.
So don't resign yourself to having only three kids. God has mysterious ways of adding additional blessings.
PS. My first two boys look JUST like me: hair color, skin tone, eye color, etc. My third son (the adopted one) looks JUST like my husband: hair color, skin tone, eye color, etc. So much like my hubby that we've actually argued with strangers about whether or not he is adopted!
