Hi I Saw My Period Twice Last Month That Is

Hi
I saw my period twice last month that is 4th and 14th because I took postinor2 twice in a month
and this month I had sex with my boyfriend without condom although I took postinor2

but within that period of the month I took ciproflocaxin and I was suppose to see my period on 13th of this month but it hasn't come although am having PMS
does that mean am pregnant
