Messed up cycle after a failed FET

Gr

We had a failed FET last month and my period came like 4 days after stopping medications. I'm currently in the subsequent cycle and my period is 3 days late. I took a pregnancy test with FMU yesterday and it was negative. I'm sure my period is coming but just wondering if anyone else's cycle get screwed up after a failed FET? My cycle is very regular with my period arriving always on the predicted date. Just annoying I guess 🙄
