Ugh Rant

Okay so I finished taking the meds I was on (metronidazole) Friday at 11.40am. That was my last dose of this stuff.

I'm currently 8 days late now from my period but both tests I had taken (one on the 5th day and one on the 7th day) both said negative on pregnancy.

I've noticed I'm extremely irritable, I'm tired a lot and I'm constantly giving an attitude. I truly dont mean it and I want to cry about it.

If I miss my period more than 2 weeks I am seeing my doctor.

However, has anyone else had this experience after this medication? Any suggestions on what to do to not be so angry or irritable?

Thank you...
