A friend of mine had no problems conceiving her first child 8 years ago she has now been trying for years for her second. Why would this happen to someone? I had a daughter 2 1/2 years ago and have now been trying for a year to get pregnant with my second. I'm beginning to think that I'm going to have the same problem as her. Why would be no problem to conceived the first time but become infertile the second?

I have a 9 year old and a 3 year old which I didn't think we would ever conceive. There are many reasons that could make problems. Are problem was I had my first child by emergency C-section and he lived 3 days. I have to have a c-section from now on. We had no trouble getting pregnant with the 9 year old but when he opened me up I had lots of scare tissue inside. When we waited a while to try to conceive I had lots more. Why I don't know they don't know. It was hanging across my tubes. Other people I know really never did find out why it took them longer. But keep trying and tell your friend to go and get some help from a fertility doctor if she has not already. As you get older your eggs do change is theory some say. Sometimes it is just stress. Ashmom if you have been trying seriously for a year I would go to the doctor for a checkup also. If you decide to seek further help my other suggestion would be to have your partner have a sperm count done. Things change and you never know it could be him too. Good luck try not to stress. I don't know if I told you this before but when we were trying for number 3 we did the big fertility drugs. It did not work. We got a puppy and 3 months later we found out we were pregnant. I was very stressed out about getting pregnant. But I'm that type of person, I stress. SO RELAX!!!

There is probably no one reason for this. Maybe it's stress, maybe your bodies are just not ready to have another child yet. If you fear that you are infertile, you should go to your doctor and be checked out to be sure. As should your husband. But just remember not to get all worked up about getting pregnant. When you stop worrying about it all the time, it will probably happen for you.
However (and I know this is none of my business but I still feel the need to mention it) try not to place too much importance and necessity on getting pregnant again. Your first child might see this as meaning s/he was not good enough for you, if all you seem to care about is having another baby. A woman I know (who was in her 40s at the time and her husband was in his 60s and had had a vasectomy!) decided she HAD to have another baby. Nevermind that she already had two teenagers, or that her husband would have to go through a major operation, or that she was really too old to be having children, she just HAD to have another baby. Not that this is like your situation, but I'm just saying that everything was focused around this baby even before it was conceived, and ever since it's just been babybabybaby all the time, and the older kids *really* begrudge it and feel kind of neglected and hurt because of it. (Plus, the child has all sorts of developmental problems.)
So I'm just saying, don't make your other kid feel worthless (not that you would) and if you do not happen to even have another child, make sure your first kid knows you are perfectly okay with that and are completely happy that you have the one.
