Hi.. I am 20 year old.. I haven't have had my periods since July. My prolactin level was disbalanced.. now in October mid I was with my boyfriend and he rubbed his penis on my vagina, some precum might be there. But there was no intercourse. It was our first time. My doc gave me deviry 10mg twice for 5days. It's the fifth day and no periods yet.. can I be pregnant? When should I do. A home pregnancy test? Please please help... scared.

You wait about 45 days after your sex experience and do a pregnancy test.

While not very likely, yes there is a possibility of pregnancy from this.
