Me and my boyfriend has sex in april and ever since my stomach has felt very bloated . i worry over everything and i think i am just worrying help. ?

Not pregnant?: Assuming pregnancy test was negative (at least a few weeks after sex), it's unlikely that bloating alone is serious. Sexual infections usually cause other symptoms like discharge, genital sores, etc. Viruses like HIV & hepatitis B don't typically cause bloating. However, further sex can certainly result in pregnancy with all its risks, as well as serious infections. Please be very careful.
