I usually have a heavy painful period every 35 days which lasts for 4-5days last month my period skipped a month I wasn't pregnant and then my period came and was really light but lasted 8 days. The day I came off my period I had sex I woke the next day I bleed alittle then stopped the same day. The next day I had sex and I woke up again and had bleed alittle and had stopped. It's now been two weeks and I'm not due on for another two weeks, but when I go to the toliet for a wee there is a tiny bit of blood when I wipe?
