Please help. Would i be pregnant?

I indulged in anal sex with my boyfriend on the 7th day of my periods I.e on 26th Jan 2017. He however did not ejaculate in me but pulled out at the right time and ejaculated at the bathroom and used tissue to wipe off the liquid . We did it thrice that day in same manner. We again did the act on 28th Jan 2017 in a similar manner. I had ipill post that I.e  on 28th Jan I.e in 48 hours including both the acts.  My last period ended on  26th Jan and I had ipill on 28th Jan and got withdrawal bleeding from 4th to 10th Feb I.e 7 days but the flow was average like that one has on the 5th day of periods out of 7days cycle. After the withdrawal bleeding in Feb I haven't got my periods as yet. Would I be pregnant ? Also m having M 2 tone syrup from today to get periods . Please suggest. I haven't done any urine pregnancy test cause m sure the act wouldn't have triggered pregnancy. Please help
