if this showed up within 10 minutes, I'd definitely say BFP! congratulations!
Nope! When I was 8dpo (9 days past BD) I got my bloods done and they came back at 7. I ended up over 45k in week 5. This time, I was at 43 two days before my period was due. It matters more if they are doubling as you know. So hopefully you can pop in for more bloods in two days? Congrats!!!
Don't worry! At 11dpo my beta was 25. If I had gone the day before I'm sure it would have been similar to you bc a digi said not pregnant and clear blue was bfn! Only frer was faint bfp. I too was worried but in 48 hrs they shot up to 127.5 and now I'm going for another beta today. The initial number is of little relevance all that matters is doubling . Congrats!!!!
