Spotting during 4-5week

Mg85

Went to the ER on Feb 26 due to spotting, did ultrasound also did blood work my HCG. Level is 253, went for my first time visit at my OB. Dr. Told me cervix is close no blood coming out... and that old blood is only in vagina. I’m still spotting here n there?!? Should I be worried?
