Same experience?

My SO and I inseminated twice in February, using the at home insemination method. Well I got my period last month and a few BFN. Now my period is a week late. Is it possible that doing the “at home method” can make extreme changes to the body? I have never been this late, I am not stressed at all, & my doctors appointment isn’t until next week Thursday 😩 has anyone ever experienced this before?? Now after 1 year of tracking my cycle I have to start all over.

Thanks in advance!!
