Good morning, so lately I haven't been feeling good very now in then. every time I lay on my stomach it makes me sick or if someone push it makes me feel sick. I get every emotional and mean to my boyfriend. I don't like to touch me and not in that way either. After i eat I feel very bloated and last night I had intercourse but I haven't slept with my boyfriend do 4 days and yesterday and today we I did my private area feels swollen but does bother me just when I whip it does and never once in my life as this ever happened so Idk what's I get my period next Tuesday btw. has anyone experience this before?
