I am current;ly 20 years old. I have never been on b/c before, and still are not. My bf and I use the pull out method. Now last month I did not get a period. I went to my gyno bc I was concerned. I have had crazy mood swings, low backaches, cramping (generally on one side), and my breasts feel sensitive and heavy. I took 5 hpt throughout the month and they all came back neg. so I told that to my gyno and she ordered a blood test. I am currently awaiting results. Also, I had last month for like 2 days some brown spotting & since that has gone and now its clear/white and milky discharge. She felt my boobs and said "Wow, are they sensitive?" and I said "yes." and then she gave me a pelvic exam and said that my uterus is enlarged (with a shocked face). She said to wait a week for the blood test results. She said I could either be pregnant or I have a cyst, even though I have never missed a period, never had a cyst and I have always been super regular. I am getting nervous and I still have 5 days of waiting. HELP.
