Okay, so I have taken birth control for the last 2 years. First, I took the depo provera, but i only took it for maybe 8-9 months. I then switched to the pills (Lutera). I have recently stopped taking the pills. By recently, i mean atleast 4-5 months ago. I have had unprotected sex many of times since I stopped taking the pill. I have no started my period since the beginning of August. I had a normal period after getting off of the pills, so I wouldnt understand why it would just disappear. I have taken many HPT and they all say negative. I had blood drawn last month and it said negative. I went to the doctor today, and it still said negative. Within the last 4 days, I have been spotting. What's going on? Should I be worried?
