Period spotting.

Hi All,

I had a wrist fracture and has taken zix p tablet for pain. After which I was asked to take cycloreg tablet for 5 days 1 in the morning and 1 at night I got my spotting on 4th day after stopping cycloreg tablet and everyday I had just the spotting for 5 days. I did a pregnancy test after a week and it came negative. We use condoms for birth control.

I Tried googeling for zix p tablet and seems like that could have caused just spotting. Can someone please help in confirming?

Can someone please tell me if it was a period spotting or something else ?
