A month ago my boyfriend and I had unprotected sex. I hadn t really had any weird symptoms until recently. I started feeling really tired and Nauseous all the time. I didn t think anything of it until this week. My periods are really irregular. I rarely have them but I wasn t sure whether to be concerned that I m late this month until I started feeling nauseous, getting sick when I eat, and always being tired. My insomnia has gotten worse as well. Any advice? I m going to take a test to be sure, but I wanted a doctor s opinion on the matter.
