Yesterday night me and my boyfriend had unprotected sex he cumed in me and the next morning when I woke up hours later I got my period am I pregnant or no ?

Honey, we don't know if you are pregnant or not. It's impossible for us to tell.

If you had unprotected sex yesterday, the sperm still hasn't reached the egg... it takes about 3 days for that to happen.

Unfortunately you now have to wait for your period to come. If it does not come when expected take a HPT using first morning urine.

But I did get my period today so what ever happened yesterday doesn't matter if he cummed in me?

You will still have to wait until next month. Most likely you are not pregnant since you started your period today. That would mean that you ovulated approximately 2 weeks ago and the egg would not be viable for fertilization at this point. But there is still a slight risk that you could be pregnant.
