Has anyone else experienced this?

[destinedtobeafurmum]

My DH and I have been TTC since January and have had two MC since then. My AF is very regular and I can usually predict when it will arrive +/-1 day. However, this month, my AF still hasn't arrived 4 days later. I've taken a test each morning and each has been a BFN. I've used the super sensitive tests that pick up as low 10mlU of HCG.

I've been getting light cramps since Saturday, which I don't ever get until AF physically starts.

I'm wondering if it might be a chemical that just hasn't passed yet and will in the next couple of days, but I'm really not sure and feel like I'm in this weird limbo at the moment.

Has anyone else experienced this?

I had the same in August, AF like clockwork but was 5 days late, I had cramping the whole time (also strange for me as usually I just cramp for a few hours on first day of period rather than for days in advance) but BFNs with the 10mIU tests. My period ended up just being late but was crazy heavy first day - I’m not sure what it was but was very rare for me as well.

Thanks for replying @Sconehenge

So just an anomaly cycle perhaps. I suspect I'll know either way by the end of this week, but it's very unlike my cycle
