6 Positive Pregnancy Test but, Still Skeptical!! Please Help!!?

My husband and I have been trying to concieve for a while now. I have PCOS so that makes it a little more difficult for me. I have tried clomid, been on Metaphornin, lost 30+ pounds the whole shabang. TIme and time no positive pregnancy test. We are in the process of adoting a baby and have become a little more relaxed and not really thinking about getting pregnant because of it. We were scheduled to do the artificial insemination at the start of my next cycle. My cycles have been pretty regular since weight loss and my tubes were flushed out around the end of March beginning of April. Well I am now two weeks late for my cycle but i have been having cramps as if its coming but there is no signs of her. I took 4 home pregnancy test last night and one this morning they were all POSITIVE :). I went to the nearby urgent care clinic just a little while ago because I was so eager and it was also POSITIVE! I am scheduled to see my gynecologist tomorrow for confirmation appointment but, I am so so nervous. Do you guys think that there is a possibility that I could not be pregnant even though I have had a total of 6 positive test!!

Praying very dilligently that this is now our time!!! Thanks in advance for your responses.
