Could I be pregnant???

I am on Lo Estrein birth control pill and I never get my period while taking it.

The last period I got was 10 weeks ago. The last time I had sex with my ex was 8 weeks ago.

We always pulled out so the only way I could have gotten pregnant was from precum.

I am stressed that I could be pregnant because I haven’t gotten my period for so long (even though I have gone months without getting one before).

Do you think I could have gotten pregnant on the pill from precum? I would be between 8-10 weeks pregnant. I have no other symptoms.
