Morning,
Wondered if anyone else had had this.
I had 5 days of prednisolone, for asthmatic bronchitis, Mon to Fri last week.
Last Monday was day 21 in my cycle, and I had 1 day of bleeding (usual for me, due to the progesterone dip). Come this Monday, 2 weeks post ovulation, and I've not started my period, but have the cramps, back ache and irritability I would expect.
3 days late now, just taken a pregnancy test (negative with the first urine of the day). Had protected sex once during my fertile period.
Cycle is usually 28 days, bleed on day 21, then normal (heavy) period. Am in early 40s, no signs of perimenopause otherwise.
Any ideas? I've read prednisolone can delay or change women's menstrual cycles, but wondered if anyone had experience of this?
