Cycle day 1? Help!

Am

Hello!

So I’m waiting to start my meds for my 2nd frozen transfer (1st one failed). I’m supposed to let my clinic know when my cycle day one is.

I’ve been spotting since Monday and yesterday it was more than spotting but not really a full normal flow. And according to this app AF was supposed to arrive Tuesday.

This is just a little abnormal for me and I’m not sure if it’s because of my ERA last Wednesday?

My clinic said they won’t consider my cycle day one till there’s a full flow.

I’m just concerned I’m getting behind and it’s going to mess with my transfer. 🙁

Has this happened to anyone else?

Any advice?
