BFP after multiple IVF failures

Diane • 31 years old. 2 IUIs, 3 IVF Cycles 💙👼🏼👼🏼💙

I finally got my BFP after my first two IVF cycles resulted in all embryos arresting. I never had any blastocysts and did a day 3 transfer this time and BOOM...i’m pregnant! Today marks exactly 4 weeks...my beta test is 97. Is this about normal? What did you guys get for your first beta??
