I have endometriosis so my periods are always irregular. It hasn’t stopped me from trying though! My last period was June 22nd and ended July 3rd. Glow says my period should start in four days. Does that seem correct? I know it only gives an estimate based on the info I put but I guess I figured since it’s been so long since my last period that a hpt would know by then. I took one two days ago. BFN. Should I try again in a week? I just hate seeing those BFN’s😔
