Could I be pregnant?

Saraniya

I need help/advice please???

So I took the pill back to back from the end of March to the beginning of July but I didn’t take it so religiously and missed days a fair amount.

I had unprotected sex at the end of June but he didn’t finish so I didn’t really worry about it and left it.

It’s now been 2.5 weeks since I’ve come off the pill and still no period. Should I be concerned? Could I be pregnant?
