Recently, my boyfriend and I had sex... But we ve done this before and he doesn t have an STD, but lately I have been getting really weird sensations when I pee, I m also worried about being pregnant cause we didn t use protection, it s way too early for any kind of symptoms but I ve also been having pain below my rib cage and I feel like I have to completely pop out my stomach to be comfortable... I ve also been oddly tired, and every other day hungrier than others. I really don t know what this could be. I don t know if it s all tied together or it s just one thing wrong in different areas...
