I had unprotected sex but he pulled out and i'm on the pill. Around the time I was supposed to have my period I only bled a very small amount everyday. I don't know if that was implantation bleeding or if my period was just extremely light. I have been having some abdominal pain and have been feeling a tad bloated. I don't know if i'm just psyching myself out or if I should actually be worried. Please let me know what you think!!
