Maybe baby?

My period is 16 days late. I’ve had unprotected sex like the flying idiot I am. My boyfriend is always super careful when he climax’s though he has never even remotely cum inside me. When he gets close he rubs off on my butt and cums seconds later. And I know pre cum is a thing but I’ve given him hand jobs and he doesn’t have pre cum

Second, I have a track record of completely stopping ovulation for months at a time. That is typically due to stress inadequate eating and fluctuating weight. And there has been a lot of that lately.

I don’t have any symptoms of pregnancy. No nausea, no unusual mood swings, no weight gain. I actually keep loosing weight.

So, should I get a pregnancy test? To be safe? And should I tell my boyfriend? Thanks in advance.
