is this normal


hcg tuesday was 88 today was 157 nurse said close enough to doubling. and is a good number for me and go again tuesday to check

ive been having some spotting on and off today and a bit of pelvic discomfort/twinges but wouldnt say cramping and am wondering if its normal. i would be 4 weeks 7 days today by last period date.

i only notice it when i wipe and its been light pink to kinda brown.

i miscarried at 6 weeks 5 days in the summer and am trying to not get my hopes up to much or stress out about this...

anyone have similar and everything turn out ok?
