Hi LMcd,
Sounds like you are so intense on getting pregnant that you are stressing yourself out over it. Relax enjoy the process of trying to get pregnant and nature will take its course. Having take all the necessary precaution of testing and having them come back ok is a very good sign. Now you need to treat your body as though you are pregnant by eating healthy, exercising, taking 1,000 miligrams of vitamin D and prenatal vitamins, start now building your body up for the new little bundle of joy you will soon have inside of you. If you like, have your partner go for testing to see if his sperm count is low, sometimes this prolong the process as well.
I have heard many stories of women doing things to conceive, one was to raise both leggs high in the air immediately after intercourse so that every drop of sperm possible would stay in...hey sometimes you have to go outside the box and try different things. Relax, be patient and enjoy the experience. It will come.
Best of Luck to you, let us know how it goes.
