Hi, I had protected sex with my boyfriend about a month ago, nearly 2 weeks later I start spotting which scared me when I read that it could've been implantation. A week layer my period was supposed to come on a Wednesday but it didn't and neither on Thursday until it decided to flow on Friday. I finished finished 2 days ago but now I'm still spotting. What could be the cause of this? I want to believe that it was my diet but I've read that some girls have had up to 2 periods while being pregnant.
