Delayed Period

Brandi

Hey ladies! I’m currently 17 DPO, and this was my second cycle taking femera at 5mg. I ovulated the 19th based on OPKs. I usually have a 28 day cycle but there’s no sign of AF. I thought she was going to start Monday after an emotional outburst Sunday, but nothing! I took a digital on Sunday that said negative. I’m too scared to take any more! Does any one have any experience with this happening?
