Pregnancy question?

I had my first time having sex with my boyfriend and he pulled out. But we didn’t use protection and I’m only 2 months till I’m 18. My period should be coming really soon but my period was like last beginning of January. And I’m scared that my period won’t be coming. I asked him if he 100% pulled out and no cum or anything near me and he said he didn’t want to make a mess and to get me in trouble. We had sex like 2 times.

he didn’t go in fully since I was in pain a lot.

Should I wait if I won’t get my period or go to the OBgyn? Im scared that I will be pregnant and my parents cannot know. I don’t want to take the pregnancy test because I don’t want to face it.

Thanks
