Went to Dr after 1 1/2 years of trying...

Well I went to the dr, me and so have been trying to conceive baby number 2 for about 1 1/2 years with no luck (baby number 1 has a different dad) we are both 23 in good condition, even after trying pre-seed, vitamins, and other stuff... doctor sent me to check my thyroid and asked to have so's swimmers checked but we can't afford what they charge here... they said we will know within a few days on the blood tests, and doing a ultrasound for pelvic inflammation. Starting to get discouraged and very depressed. I'm not sure how much longer I can keep being disappointed every month. Ugh
