Another SCH?!

I’ve had 3 BLighted ovums (misscarriages) in the past, last one was in feb 2021. I’m currently 5 weeks pregnant, went on Thursday for a vsginal ultrasound and they could see nothing in the sac yet she said it’s normal to not see nothing so early on. I have to go back in 2 weeks when I’m supposed to be 7 weeks. Thing is on Thursday I started to bleed and it’s been off and on ever since between light brown like old blood and pink/red like new blood. I’ve been down this road before way too many times 😞 going to call the doc tomorrow if they can draw my hcg levels or perhaps but me in for an ultrasound this week instead of having to wait another 2 weeks. I’ve had a SCH in my previous pregnancy at 11 weeks and he’s a healthy 3 year old now. Could it be happening again?! Has anyone bleed throughout their pregnancy and had a healthy baby?
