Hi doctor! [URGENT]

I would like to know if I can get pregnant because me and my boyfriend had anal sex yesterday and did not use pills or condoms... he put saliva all over the enter and his penis as lubricating. First, when he put it in me he was not hard. he did not ejaculate in me, he pulled out in time. But I did touch around my vagina just to see if he put it in the right hole and I remember my hand was not wet that much..I am very shy and neither of my parents know about it (I can not talk to them about things like these) so going to a gynecologist or other does not work for me... I am supposed to start my period on Sunday or Tuesday. I do not feel anything weird, I am just really anxious about it.

I hope you can help me... Thank you doctor!
