AF Late

I ovulated late this month on CD16. I usually have a 28/29 day cycle but had a MC on 20th Feb and this is first AF due since then.

Ovia & Fertility Friend saying my AF shpuld be due today but the witch hasn't arrived. I'm currently 11dpo but has some light spotting on Tuesday (8dpo) & Wednesday (9dpo) which I thought was AF coming early as has quite bad cramps but nothing 😕

I'm now thinking (absolutely hoping) that it was an IB. I tested today but got a BFN. I've now done some reading and looks like it can take almost a week from the IB to get a BFP 😭 means I'll have to wait until about Tuesday next week before I may get my BFP.

This waiting is so frustrating :(
