I got my period on May 1. I bled for 7 days. Then after that a couple days later I was bleeding again but it was really light. It was brownish. I would only see it when I would wipe. I have never had an irregular period before. I got a mirena IUD not even a month ago. About a week before my period my boyfriend and I had unprotected sex and he went inside of me. I'm not sure if maybe it's from mirena or if it wa implantation bleeding. The only other symptoms I would have of pregnancy is being more tired than usual I have been peeing more frequently and I am really emotional I will cry over nothing and don't even know why I'm crying. Just not sure if I should take a test or if it could be from my mirena.
