I am new to this board and just wanted to say HI! So many abbriveations to learn on here

hopefully I'll get the hang of it soon. Since I can read so much about all of you I figure I will share my story with you:
My DH and I got married in June and I went off the pill in July so we could start TTC. I had my typical August period and then not another one. I have taken more pregnancy tests then I can count since then! I went to my OBGYN in October for my yearly and they had me do some bloodwork. December I found out I was insulin resistant and that was probably the cause of me not having periods. I started metformin in December and met with a nutritionist. At my checkup in Jan. I still hadn't had a period. My doctor said I should start after losing about 10% of my body weight, but I had already lost 20% so I was frustrated. I kept up my diet and metformin and have lost 25% of my body weight. I look and feel great and I finally had a period March 4th. But now its April 15th and nothing. I have taken 3 pregnancy tests, all negative. I don't have another appointment until late July with my doctor for a checkup. I am currently very frustrated with my situation but I am trying to look at the bright side of things but it gets hard some days when all I see is pregnant women. Also, my best friend recently found out she is pregnant with her 3rd 'opps' (she calls them that) and not so happy. Its frustrating that she can get pregnant so easily and not want to and I want to and cannot. I'm sure many of you have felt the same way from time to time which is why I wanted to find some place that I can share my feelings with.
Wow, if you made it through that hello! Thanks for letting me into your community. In order to help me out some if you could reply with an abbreviation and its meaning that would help a lot
