Can this have an effect on my period?

Question

I have been on Minocycline for about 3 weeks now and my boyfriend and I got close to having s*x, but never had it. (I'll give the situation at the bottom) And now my period is late? Could Minocycline affect my menstrual cycle? In case you didn't know, Minocycline is an oral antibiotic for acne.

Oh yeah, here's what happened:

Answer 1

So you almost had anal s*x but not intercourse???  Um -- talk to your doctor, planned parenthood, health department, whoever -- if you are old enough to do anal, your old enough to discuss it with a gynecologist.  Trust me, it is VERY normal to do and worry about you're going through.

With that said, it is most likely the stress.  It is amazing how worrying about it can make it late.  It can push mine back 5 or 6 days easy.

My sis and I have never had a problem with minocycline holding it up and we are middle age women been using it since we were teens.
