2 weeks pregnant cramping and spotting.

I am cramping and spotting (brownish blood) my cramps are on and off for two days now nothing horrible but still worrying me. I have been getting my levels tested every 48 hours and they are slowly going up. I am in hormone pills. I have had a miscarriage before. Hoping all goes well and there is nothing to worry about. Anyone have a healthy pregnancy and this same issue? Picture is of my first transvaginal ultrasound the black dot is where the baby is you just can't see anything.
