K, be real?

So me and my boyfriend had sex again while I was on my period well it's my fourth day so like it's just the brown discharge . We used a condom but the condom broke . Man I'm freaking out , I google some stuff it says you can probably get pregnant depending on your length of cycle well mines like 26 and I have it every 3 weeks . & Glow didn't say anything when I complete my log in.
