Ok so my boyfriend and I have been together on and off for five years recently I discovered that he was talking to other women so I went out with a guy unprotected :( there was alcohol involved sadly... a week after I got a std check at my ob I guess while I was out this evening the ob office called me back and told me to call in.. I'm freaking out because my the time I got it the time was 9pm and it was to late to call them there's a billion things running through my head... if I have an std how do I tell my boyfriend? What do I do? Do u think they are calling about an std I'm scared to tell my boyfriend I hooked up with someone please help:(

Yes most likely that is what they are calling about, You just won't know till you call them back.

Most likely boyfriend will think he gave it to you,
