I started my cycle on June 10th and my last day was June 14th (no bleeding at all after about 5 pm). My boyfriend and I had sex on the 14th, that night/morning (some time between 12 am and 2 pm), showered and went to sleep. When I woke up that morning, my cycle was back on. I woke up with blood in my underwear but for the rest of that day and up until today (just stopped), I've only been spotting or seeing blood only when wiping. Can anyone provide any information on what may be going on?!!
