Had sex with my boyfriend on valentines, started off with no condom but after a minute he put one on. He finished in the condom no breakage. Today I threw up this morning and feel like shit but I think it could be from my food last night. Ended my period about 2 days ago and it is always everywhere very abnormal periods. Please tell me if I'm being paranoid. UPDATE no throw up this morning and a few others that went with me to the buffet had a stomach ache and diarrhea
