H E L P Again Ladies🙈🙈😔

Ok so this might be a bit stupid,but I started my AF yesterday morning. I was over my SO house. He had just made it in from work but anyway. I woke up and felt really moist. So I check it was nothing then when I check again I was bleeding. So he went to get me pads,and everything an was really understanding actually. Even though a little had gotten on his sheets only because I was naked. Oan: it slowed down almost to a stopping point and this would be my second day. I'm not sure whether or not if its normal. I'm completely lost right now. So I figured I'll just wait and see what happens from here on out. It's totally weird though,because I normally have a four to five day AF. Any suggests are welcome thanks in advance ladies. 😘😘
