I'm currently on Birth Control and anitbiotics. I was having sex with my boyfriend on Sunday and the condom broke Im worried about getting pregnant. Should I get the morning after pill. Or should I be OK because my period is due Thursday.

Get the ECP. Pregnancy is always a possibility, even with the pill. Since you are on antibiotics you risk is increased.

Yes I would opt for the ECP also,
The pill is not 100 percent effective and less on antibiotics. But remember the ECP is only for use once in a while and can not be taken often close to each other
