Spotting

We had FET on the 3rd of April and for the last week I have been spotting. One day it was a reletively shocking amount (covering the toilet paper with two wipes) then nothing for a day or two. Now it's been almost daily (1-5 times/day) small spots. Usually light pink - brown and occasionally bright red. Plan for now from my fertility team and my OBGyn is to get an Ultrasound on Thursday this week (7 weeks to confirm heartbeat). We have a history of recurrent miscarriage with one successful pregnancy. Has anyone else had frequent spotting and come out fine on the other side?
