I have not been having a period for the last two months. I went off of both control completely in September, and had cycles that were approximately 40 days long. My last period started on February 10th. on February 22nd, i started taking birth control pills again, but stopped after 2 days since I decided I no longer wanted to take them. I had some spotting on February 27th. On March 19th, I had unprotected sex, and there was some spotting afterward. I did not have a period during the month of march and I have not had one yet in April. I have taken 2 pregnancy tests, one on April 14th, and one today, on April 27th, and both were negative. I was just wondering what might be causing my missed periods.
