late period.

C.
My period is three days late. Having period symptoms, cramping, sore boobs but no bleeding. Just discharge. I took a pregnancy test but it was negative so I don't know what's going on. 🤔 I've never been late before. Could it still be too soon for a positive pregnancy test? I had my bachelorette party last night and drank quite a bit so I'm really hoping if I am pregnant and just not getting positives yet the alcohol didn't hurt anything. ☹️️
