Help?

Sarah

So, I'm 19.. been with my boyfriend for almost 9 months, and we've been having sex.. usually pretty safe.. I know shame on me, but condoms are expensive.. and his pull out game is pretty strong.

Anyways, I'm only 3 days late on my period.. but I'm usually really regular, like every 28 days on the day..

I guess all I'm asking is what should I do? I'm really freaking out, tbh.. any insight on what to do? I'm not ready to be pregnant and have a child of my own..
