2 && Half day Period

This is so strange😳 so I started to spot on the 21st late that night so I get up shower and it's the 22nd I wipe an see pink as if my cycle is starting but loving a bit slow🤔🤔 so here's the 24th (today)early this morning and it's completely gone as if it's never been there😳WTF is going on😩😩 I normally always get 5to6 days none stop and I'm already experiencing strong flutters frequently as if I'm pregnant,but I know that I'm not😔 I'm really starting to consider a trip to the doctor😔🙏🏽 any suggestions ladies because I'm thinking the worst at this point
