My bf has never climaxed in me or on me, and we are always very careful to clean up and use spermicidal condoms. I recently traveled stationary in the car for a couple weeks into a way hotter climate than normal, and when I got back on little sleep, I drank alcohol for the first time. I got intoxicated and nauseous from that. The nausea lasted into the next day and night and I started light spotting. This is right around the time I should be having my cycle... Is it possible I need to buy a test or could the stress on my body be causing this?
