Saturday night I noticed I had an extremely low tolerance of alcohol (almost puked from 2 shots of tequila) and a streak of old blood in my panties and last night the spotting has continued now its light pinkish and barely noticeable. I am also experiencing cramping and the feeling that my period is coming on full force but every time I check its nothing. Along with that I have sore breasts, dull headache, backache no energy. I did have sex a week before up until the day of my last period (july 22) unprotected so Idk if that could have a played a role in this early light bleeding? I'm expecting to see my period on the 18th so maybe the flow will increase over time?
