Excessive spotting

Hi all,

Recently I was given azythromycin for an infection, it was at the beginning of a new BC pack. Towards the middle/end of my pack I started spotting (enough to need a pad) for about 10 days, up until my period started. My periods over and bleeding has stopped.

Has anyone else ever experienced excessive spotting like this? Could it be from strong antibiotics affecting the hormones? This also happened to me a few months ago, but I thought it was because i skipped my placebo pills that month (I know, stupid, but had a hot date and was in a super long dry spell at the time 😂).

Anyway,do you think that this is normal or should I bring it up to a doctor? I wouldn’t be too concerned but I feel like spotting shouldn’t last that long.

Thanks!
