Femara/Letrozole twins


Hi all. Just curious. Anyone pregnant with twins after femara? I read that the risk of multiples is lower with femara than clomid but I was just wondering.

Im almost 5 weeks, My hcg doubling rate is 37 hrs so far and my Progesterone is 52 and I broke out in hives which I read are signs of multiples (and we with Pcos can have multiples) but I know that obviously it could just be a Singleton. Just curious if anyone in here is having twins! Only time will tell for me. Fingers crossed for a sticky bean(S)!
