Hey ladies. So, I had some back pain and some light light spotting today. I am on cycle day 8 and have a 28 day cycle, but my last period was only three days, as opposed to 5 or 6 and was really light. I also have had sex about every other day for the last two weeks. Is it possible to maybe have sex just before my period, but not implant until now? I’ll obviously take a test tomorrow morning probably, but I just wanted to know if anyone had anything like this happen and found out they were pregnant or if they think it looks like implantation bleeding.. thanks in advance! 🙂
