Ok, so back in august my health provider sent my pills late, which lead to me going my first week without pills. Once they came in, I doubled up to catch up, then finished the pack, and got my period as normal. The next month I took the pack as I normally would, not missing any and keep the times in control. I also had sex a few days before my "expected ovulation" but had not missed pills or anything. But my period came 4 days early during the third week of pills, then lasted until the next thursday, which is when my period would normally end. At first it was spotting then heavier bleeding. During that week it ended I had sex with my boyfriend (no condom) since i was on the pill and took it religiously, then about 4 days later had slight spotting. My month then went along as normal and I am now seeing brown/greyish chunks when I wipe, with slight brown spotting. My period isn't due for another 4 days..is this normal? should I be worried? is my body still adjusting? could it be pregnant because thats the last thing I need, help?
