What causes late cycle? My period is 2 days late as of now, last month a day late, and in march I was almost 2 weeks late but February a short month so I had a period Jan 30-feb 3 & feb 27th- march 3 and period started again on the 6th of April . Also negative pregnancy today Not sure what’s going on and no I can’t be pregnant last time I had sex was on the 14th so a pregnancy test would’ve been picked up by now
