Late period

Okay, so I’m starting to freak out a bit because my period has been on time, maybe a day early for the last 8 months or so.

I haven’t started it yet, and it would’ve been ending around this time. I had surgery in December and had like 6 pregnancy test because different doctors ran different tests.

I also had sex, with a condom a couple weeks prior in December. I honestly don’t know if the condom broke or had a hole and I haven’t spoken to the guy since because he disappeared on me.

Post-surgery, I had some issues with the healing in my bone and had to start Calcium-citrate and Magnesium pills. I’ve tried looking up different articles to see if that can causes issues in the mensuration cycle. I haven’t found anything that says it delays it, but apparently it helps with the cramps.

Has anyone ever had a similar issue with those types of pills?
