I don't know all of the correct terms and what not. I just know I typically start my period on the 28th of each month. My husband and I had unprotected inter course on May 20. I started having spotting 3-4 days after that. Super light. Sometimes pink and sometimes light brown. I had one particular day where the spotting was light brown with some blood in it. It has been a couple days on and off. I have zero signs of my period coming. I will typically start pmsing about a week before I start my dot. Nothing. Nothing at all. I don't have mood swings or tender breasts (which I always have when pmsing). I've just been super tired. I've taken a pregnancy test and it was negative. Anyone else experience this before?? Let me know!
