Scared I’m pregnant

So I’m patiently waiting for my period Thats supposed to come in 6 days or so .

And I had protected sex at the end of October or early November idk .

And I spotted 2 weeks before my period on ovulation day and I’ve never done that before . But he pulled out and there was no cum only pre cum if anything .

Idk if it’s my anxiety but I feel like I have a heighten sense of smell my boobs kinda hurt slight cramps and mood swings .
