HCG tripling in 48 hours

Ash

I had blood taken in Friday to check HCG levels and they were 740. I had another test Monday and they had risen to 2700!

Has annoying else had this? Is that normal/ok?

I think I’m 5 weeks 1 day but have had weird periods and cycles for the last 6 months after I came off the pill so could be further/less.
