I've been on the pill for three years, but I tend to miss days quite a bit. Me and my boyfriend have had unprotected sex a few times now, and this month my period was two days late and when it finally did come it was lighter than usual. Lately I have noticed my abdomen is bloated and seems to be hardening, my boobs are not sore, but they feel harder. I'm sleepier than usual, I have what feels like menstrual cramps but I am nowhere near my period, and I've been making more trips to the bathroom. My apatite has changed slightly, and my gums have bled on one occation. I bought a HPT thinking for sure that it would be positive but it turned out negative, (I did have it held instead of laying it down flat like was supposed to be though). Would that have had anything to do with it? Today I also have lower back pain, and diherrea (TMI?) to add to that list. Any thoughts?
