Could I Be Pregnant After Taking Emergency Contraceptive?

Hello doctor. Me and my partner didn’t had sex. On July 4, gave him oral. His pre cum got onto my lips. Kissed him on his hips with his pre cum. And then he went down on me. Is it possible to get pregnant like that? Or even if he has touched his penis with a little bit of pre cum and fingered me after 1-1.5 hours of doing so? I took emergency contraceptive under 48 hours. And I drank 2 glasses of ginger water one day before taking it and also 5 hours before taking it. And early morning before taking the pill on July 5, I saw some light bleeding in my vagina and thought it was ovulation bleeding because I don’t have such light periods. And I’ve irregular periods. ( I’m not sure if it was my periods ) so there are chances that I took the unwanted 72 pill on the first day or 1-2 days before my periods were due. And after 14-15 hours of taking the pill, I started bleeding heavily (more than spotting and less than periods) . The bleeding was enough to use a pad. Can withdrawal bleeding start this early ? Just after 14-15 hours of taking the pill? Or is it my periods triggering early because I took the pill maybe near my due date or on my due date? On 6th July morning, I drank one more glass of ginger water , and in the evening my body temperature fluctuated between 99.3 at 5pm to 98.7 at 8pm and 97.6 at 11pm . My heartbeat also gets fast sometimes. Is it because of the stress? Or hormonal changes? Today is July 7th, more than 48 hours gone after taking the pill. And in the morning , I was feeling dizzy , tired and weakness. I slept again and woke up at 3pm. I am still feeling tired but that maybe because I slept so much. I’m still bleeding heavily. But it’s lesser than my normal periods. Could this be my periods only? But less heavier? Or is it withdrawal bleeding? Am I pregnancy safe? I’m really worried!
