Finally got to the OBGYN

Not the best pics but now my official Due date is September 19th 2022!! Couldn't find out the gender because baby wouldn't open their legs lol had this problem with my last two lol but anatomy scan should be with in the next two weeks so I will find out then but I was kinda bummed lol have two girls hoping for a boy. Heart rate was 143 both my girls were almost 160 so let's manifest a boy! 🤞 first pic is of a leg and second is the heart with heartbeat 💓 Also I'm 21 weeks and day and baby is measuring about a week behind is this normal for anyone else? The OB said baby looked perfect tho.
