Hi I was suppose to start 2 days ago but last night I noticed I had some light brown discharge. Not a lot. Enough to be in tissue when I wipe. I usually have a 26/28 day cycle since coming of the cerazette pill in December. I usually get some light spotting before my period. The only reason it's making me question is because I believe I ovulated late. I had unprotected sex a week ago today and today I'm nauseas and slightly light headed. I know this could all be pms as I do suffer with it but has anyone had this and been pregnant? Iv never had implantation bleeding neither x
