I'm not sure if anyone will have any info but I thought I would give it a shot.
I am not yet 4wks based on LMP. Used the Clearblue advanced with weeks estimator this morning and it said I'm between 4-5wks. I guess my question is if anyone knows the HCG ranges for the weeks estimator? I'm dying of curiosity to guess my betas because my last pregnancy was with twins.
I had lab work done today but, like I said, just curious and playing home detective.
*ETA: yes, I know, betas are not a predictor of multiples, only an u/s can tell. ;)
