My last period ended 33 days ago. My nipples are very sensitive. I have slightly inverted nipples (not fully inverted, but not "normal") and occasionally I have noticed a white discharge (it never actually oozes out or comes out of my nipple but it does go away). I have been feeling nausea on and off throughtout the last few days. I am also quite heavely medicated (bare with me with the spellings, i'll spell them how they sound) i'm on amitriptaline for migranes, prozac for depression, epival for mood disorder and have been for a few years (except the latter... it's been about 2 weeks). After my last period I didn't pick up my birth control but my boyfriend and I had sex at least once a day for approx. 2 weeks. I took an at home pregnancy test (a digital one, like a thermometer, that when it had the result it read either "pregnant" or "not pregnant") it had 2 sticks you inserted into the front and peed on. Neither worked (the screen always said see leaflet) but when i removed the sticks, each one only had one line on it so i thought i was safe and not pregnant. I have yet to have my period. I'm not sure what to do. Could it be something else?
