Ok so I’m worried, I had unprotected sex a few weeks ago and took Ellaone 2 days later , stupidly bad unprotected sex again about a week before my period was due and didn’t take another pill.. now my period hasn’t arrived, but I’ve been having period cramps, my cycle is usually 30-32 days , I’m on day 39 now and still nothing but cramping for 4 days , I did a test on the 34th day of my cycle and it was negative .. could it be a false negative or is my period just delayed .. any advice guys ?
