UpSpring Fertility+ Late Period?

Has anyone taken UpSpring Fertility+ and ended up having a super late period? I’m now 4 days late, and I’ve been away for 4 weeks so the last time DH and I BD’d I had just finished my period.

There’s no way I’m pregnant (I’ve taken tests just in case that 3% chance ended up being our miracle). I’m wondering if it’s a side effect of the new medication, but I can’t find it online.

Has anyone else experienced this?

I thought I’d be close to ovulating by the time I got home next week 😭 I just want my period to start!
