condom broke inside me, what do I do?

Lily

Ok so today I had sex with my boyfriend and the Condon broke inside of me and I'm scared that there was pre-cum at the top of the condom and that when it broke it went inside of me, it is also the first day of my fertile period so I'm really stressing and I've only been in the pill for about 5 days now so not enough to protect me, someone advice pls ?!
