am I pregnant

so my boyfriend has been coming over on the weekends. Last week and this week we had sex. But my period tracker said i saw supposed to start yesterday. But I didn’t and I didn’t start this morning. I’m starting to freak out a little.

but i don’t really know the signs for pregnancy and I’m praying that I am not.

Help??

How long does it take for me to know.

I don’t have the resources to get a test?
