No sign of periods. I pill. reply asap!

It was her 5th day ending of cycle n we had some dry humping and then we tried anal bt as it was painful so before proper insertion of penis in the anal we stopped bt i ejaculated a bit near the end of her anal area n then we wiped it n washed it straight away n after that in 48 hours she took i-pill as and after 7 days she noticed very light bleeding... Usual dates of her period is 28 to 2 of every month like her period of February came on 2nd and of march came on 12th march and now it is 16th april we tried a heck of papayas and cinnamon powder and cloves for bringing it on time but we found nothing helping... Is she pregnant or it is the effect of that ipill... It was the first time she had took the i pill... Reply ASAP
