Congratulations!! What a wonderful surprise. Which my DS we struggled some (did not end up having to do IVF but it felt like forever) and so when we found out i was pregnant this time not even trying it was exciting to be sure, yesterday we just found out we are having twins so it is even more of a surprise.
Sounds like you are right on track. I know it is very hard not to worry but I hope that you can find peace knowing you saw the right things for how far along you are. Good luck and I hope you have a great easy pregnancy!! Welcome to our group.
