N.S.
You should look up secondary infertility - it is NOT only with the 2nd child. It is any attempt after the first child. There is a lot of information out there on it. Just check it out.
As for secondary infertility, I have two friends who had the exact same problem after their 3rd and 4th's. Then afterwards, they got pregnant fine the next times. It has to do with a lot of things but I do know that it took them about a year before anything. And they were quite worried...
It is not easy no matter what number it is and just hang in there! I know its hard...
Your hormone levels are probably off and maybe a few things would work or atleast assist - accupuncture or chiropractic work. There is a high rate success with 2ndary infertility with accupressure and puncture. You may want to look into it and if you need the name of someone who is really really good and effective I can give it to you. She worked on me for something OB related and in the 1st try it succeeded. I also know others who have gotten pregnant with it. I would write more but GTG. If you want mroe info please let me know. Good luck and hang in there!
