HCG question


Ok ladies... my doctor wanted me to take a hcg blood test and then do another 2 days later since I've had a miscarriage in the past.

So, I took the first one at 4 weeks and 1 day.. then I took the second at 4 weeks and 3 days. My results are 4w1d- 910, and 4w3d- 3,610.... so do you think this means single or twins?

I already have 2 children.

We have an ultrasound next week for 6 weeks.

I've seen various posts as to singles and both twins.. so I'm just curious haha I know only the ultrasound can tell but it's fun to think about both ways
