Pregnancy

My period is late by two days, normally this wouldn’t be an issue because my period sometimes is delayed and only lasts about 2 to 3 days. This time it’s different, me and my “boyfriend” slipped up about two weeks ago and the condom broke. We caught it before he finished but it still broke... I’ve been having light cramps and I’ve been extremely sleepy for the past four days. I’m even having white discharge (no not an sti or std we get tested all the time). Maybe it’s stress? Idk he haven’t talked to me in two days and won’t tell me the reason. Honestly I’m sick of his mood swings. I was getting ready to break up with him, unless I’m pregnant. I’m going to give it at least three more days before I buy a test. I’m 22 so having a baby right now isn’t scary or anything, I’m also financially stable. It’s just the current situation I’m in that’s making me unhappy.
