Could I be pregnant??

I’ve been the pill for 3 months, my doctors messed up my prescription so I missed starting again on the right date, when I did get them it was about 2 days late.

I read a thing on the internet and in the pill leaflet if you start the pill between days 1-5 of your cycle your covered straight away.

I started again on the 5th day, am I protected??

Me and my bf has sex and he came inside but now I’m abit worried I could get pregnant.
