First us large gestational sac

Na

I just had my first us ever at 4 weeks and 4 days and the doctor says that everything is fine and that i am at 5 weeks and 3 days ..even though he did me <a href="https://glowing.com/glow-fertility-program">ivf</a> so he knows the exact time of the transfer and all , but he wrote that the gestational sac is 15mm/14mm with a large diamètre...

So this made me very worry i ve been looking through google and nothing is good so far...he said to came back at 10 days max so any ideas... Realy tearing up of loosing the only chance to be a mother
