meds that mess with period

I got diagnosed with bronchitis last week. I got a shot of a steroid to help and got put on another steroid for 5 days (Prednisone). last day to take it was yesterday. my period is due today and it hasn't started. has anyone had any issues. we are ttc. I will take a hpt in the morning if I haven't started I just wanted some opinions.

on a side note. may be off subject but my body aches, hot flashes, really oily skin, boobs hurt. Idk if these would be signs but I'm kinda hoping.
