I had my period twice in November(October 29-November2) & (November24-28). Both periods were normal. December 1st I had unprotected sex but he did not have the chance to have ejaculate. I use this period app to keep track of my cycle & it says that I am 4 days late. Earlier today I was spotting (pinkish). And now it has completely stopped, could someone give me some advice on this?
