Pregnancy

I’ve been taking Metformin 500mg twice a day to help me regulate my periods and help me ovulate when I’m supposed to. I’ve been on it since late March and I’ve gotten my period on time when I’m supposed to but still haven’t gotten it yet. We are trying for baby #1 and we had sex 3 times during my fertile window including ovulation day. I’m 4 days late now and am waiting to test until Friday but what do you guys think my chances are that I’m pregnant? The only symptoms I really have are bloating, fatigue and some nausea here and there. Anyone’s option is appreciated! 😊
