The more you stress over it - even with the help of chlomid - your body won't let you get pregnant.
We did 4 months of chlomid - for me personally - it was WONDERFUL!! My body did EVERYTHING it was supposed to - yippee!!! However, we never got pregnant on it. We took the fun out of having sex and made it "we need to do this NOW so we can get pregnant".
It was only after we totally gave up - no more tests, temperature checks, drugs, etc. and just LIVED our lives did we get pregnant. We got a dog and six months after giving up I got pregnant - since I wasn't THINKING about getting or being pregnant, I thought I had the flu - that's when I found out I was pregnant.
GOOD LUCK!!! I hope it all works out for you!!
