Anyone else ever have this? I've had some really wonky cycles since af returned & this really threw me for a loop...

First cycle was 25 days (gave me a beautiful chart), next was 18, last was 39, and now this one. Two days ago, day 17, I started bleeding definitely more than just spotting so I put it in my ff app, then it just stopped... nothing yesterday or today.

We use condoms so I don't really suspect pregnancy or that it would be implantation bleeding BUT I know that it *could* still happen. We still bf quite frequently through the day & night too so I'm sure that messes with my hormones as well. I'm just wondering if anyone else ever has this?
