Clomid and our journey TTC

So we have been Not-preventing for 2 years and TTC for 1.5 years. I've had lab work done-all was normal. We've used pre-seed, Geritol I've taken PNV. My MD told me to stop <a href="">tracking ovulation</a> because it was stressing me out (i've never had a positive).  He gave me a prescription for Metformin  but it upset my stomach so bad I couldn't take it. He offered to give me clomid that visit, but I didn't take it because I felt like that would really make the infertility real. My husband and I have an appointment on Monday with an infertility specialist in hopes that I can get the Clomid prescription. Does anybody have any advice for taking the clomid. What about the ultrasounds. Did you do that or not..and what is your experience with that
