Please HELPPP!!!

First positive on last sunday!!

This a few days later (and a ton of other positives frer and clearblue +.. but a negative-on clear blue digital))

Went to hospital for blood work yesterday- hcg test said 4.4 and dr said not pregnant!!!

Came home test again and got this one on left with pink marker.. the one on right side is from this am fmu!!

This pic was also yesterday pm and this am.. the one with pink marker is yesterday and the one with no writing is this am fmu??????

Am I having a chemical pregnancy???? Or has anyone had this happen and still a good outcome? My period is due wed????
