Broken condom

Me and my boyfriend had sex 2 days ago with a condom but there was a massive rip in it. He did cum in me because we didn’t realise it had broke. It happened around 4 days before my next period and I’m not on any birth control. I’m meant to start the pill at the beginning of my next period which is due to start next week. I haven’t taken any emergency contraception because If I am pregnant Me and my partner would be fine with it. I’ve had lots of watery liquid coming out of me ever since it happened what does this mean? Also what are the chances I may be pregnant?
