Anyone?!

Hey y’all! So I’ve had some light dark red bleeding (same thing happened during my first pregnancy and all was well) and so far everything looks good with this one too! My HCG levels on February 15th were 1,388 and on Tuesday the 20th they were 9,194. The lady who does the sonograms at my Dr’s office is a B-word and never told me what I was looking at here. I thought there was only a gestational sac but I’m pretty sure the dr mentioned a yolk sac as well. I’m going back next week but I’m just really curious as to what exactly is there bc a week before there was nothing! Thanks everyone!!!
