Early Pregnant after losses

So I found out I was pregnant on Monday when I was 10dpo. I think I ovulated like a week or so early so I was only three weeks exactly on Monday from my last period. I have noticed that the lines are getting super dark super quick like more quickly than I’ve ever seen before. My doctor ordered a blood hCG test and it went from 20 on Tuesday to 64 on Thursday. And the test I took last night was on the verge of being a dye stealer, if not slightly darker than the control line. Picture for reference. I have a strong feeling it’s multiples due to how strongly I’ve been feeling symptoms and everything. Has anyone else had the same experience and it be twins or more?
