I have been on mixed hormone birth control for three years now, and last month (in june) My boyfriend and I had sex without a condom one whole week before my period started.He did not cum inside me or even get close (He is slow to get there... very slow... ) it was for less than a minute... Well the week after I did get my period but it was very dark and very clotted but it lasted the same amount of time ( five days, the last one being almost totally gone..as usual) I have not felt any different other than today when I discovered that only my nipples are sore but only if i pinch at them, not the rest of my breast or areola... I am used to a bit of pain about a week before my period but only every now and then... (and it is a week before my period starts right now) ... I am wondering If I am just being paranoid about this or if the stress is having a serious effect on me and is taking a tole on my mind...
