last month my partner and me had unprotected sex a number of times, some he finished some he didnt, the ones he did I wrote down on my tracker to know for sure, yesterday he did and when I went to bed for the life of me I could not get comfy on my tummy, my breasts were achingly sore that I had to lay on my back, this afternoon I notice a string of discharge but more blooded (sorry tmi I know) and I have been bleeding now quite light with no cramps, mega bloat and my breasts are still very achy, my mood I feel quite calm but I can just snap if someone tries to argue with me (partner) took a test and it was unclear but I think it was negative.....does this sound like it is my period ladies please
