Pcos OR Period?!


I’m not one to post for help, but here it goes. I’ve been diagnosed with pcos 6 years ago. I haven’t had a period for 5 years. My now boyfriend and I have been having sex more often then we should. I’m not on any birth control. We don’t use any protection. Two nights ago we had sex, when I came home I peed and notice a light light spotting (first time seeing this for five years!!) I thought I just had lying eyes. Thought I was just tired. Well, yesterday I peed and noticed it was a little more noticeable. Still light. I panicked! Could I be pregnant?! Or am I finally having a period with no help?! Can sex help!? I need opinions! I need help!!
