I’m 40 years old and currently 4wk2d pregnant with my second child. I had a positive urine test on Monday (test on Saturday was negative) and then had my blood taken yesterday.
I got my tests back today and I have an HCG of 191 and my Dr has asked me to redo them in 48 hours to make they’re doubling. I’m feeling nervous that this pregnancy won’t stick as I had a chemical a few months ago. Can anyone share their positive stories with me?
My period was due yesterday although timing could be slightly off as my period is still irregular postpartum. Feeling very nauseous today, did a clear blue digital and it said not pregnant but then took a FRER and got this very faint line or is it an indent?
