I am sorry you are going through all of this! I understand.
My husband and I tried for 8 years. During that time I had 4 miscarriages at around 7-11 weeks. It was truly miserable. During this 8 year period I was diagnosed with hypothryoidism, PCOS and my husband was told he had low motility.
I started taking meds for both of my conditions and my husband had surgery to help with his problem. I then did 2 rounds of Clomid. That was miserable. I never even ovulated and it kicked my hormone levels over the roof...I was truly ready to physically harm my husband. So we stopped that real quick.
At this point I gave up for awhile. Then we went to a new doctor. I had all kinds of test including a hystogram (which was just blah). I had no blockage of the tubes and my cysts on my ovaries were confirmed. There was still no reason we could figure for the miscarriage. We decided to do injections and IVF. However, the more and more I thought about it, the less and less this is what I wanted to do.
Soooo...another doctor. He reviewed everything. He sent me to have more bloodwork. He told me he thought I might have thrombophilia...opposite of hemophilia. That is that my blood was clotting too thick and therefore the embryo could not attach to the siding of my uterus (which typically happens between the 5-8 weeks...or so he told me). He told me this would explain me getting pregnant but not keeping it.
I though oh great another procedure or more medication. No, he told me to start taking an aspirin a day (blood thinner). Not a month later I was pregnant again. However, I was not excited...had not made it past the implantation phase yet.
Well, just to tell you, my beautiful miracle of a son just had his 2nd birthday.
I share this with several of my friends that have had problems getting and staying pregnant. It does not hurt to try...heck an aspirin a day is actually recommended after a certain age for heart health!!!
Good luck!
