Query on Pregnancy. In future pregnancy?

Hello, Me and my girlfriend had Intercourse on 7-March-2020. We used condom however after Intercourse we saw that condom is broken. As a precautionary measure she took I-Pill on the same day. Next Day 8-March-2020 (after around 21-22 hours) we consumed wine and she womitted after that. Her period date was 12-March-2020. We tested using Prega News pregnancy strip on  twice 16-March-2020 and 17-March-2020 and the results is negative however we are worried now as her periods has not come. She observed some thick blood on 10-March-2020 from vagina but it was not periods as it got stopped immediately and the blooding was not proper. Is she pregnant? In case of pregnancy, can abortion be done by medicine? is it safe? are there any side effects? does it leads to complications in future pregnancy?
