Okay, So I have an irregular period, Mine skips a month and in December I had my period and so I wasn't supposed to have one this month (January) and I had one. The first 2 days were so heavy I stained my underwear no matter what I wore, the next 2 days were very light so I and my boyfriend decided to have sex, the next day my period stopped. So for the past two days, I have been spotting for like a couple of hours and then it goes away. I only see the blood when I wipe and it doesn't get on my underwear. Could this be implantation bleeding? My sister said the same thing happened to her.
Yes, I and my boyfriend had sex a week before my period started.
