Hello, was wondering what your thoughts are on my situation. Ive been having done nausea accompanied by loose stools and what feels like menstrual cramps all in the last week. I am 8 days late for my period which is uncommon but I did take plan b oct 30 after an episode on oct 28. I was also on birth control but was taking amoxicillin . Do you think I have a good chance of being pregnant or could plan b really delay my cycle but cause these symptoms?
