Panic attack!!

Soooo my husband and I got married in April, and went on honeymoon in September (just got back like a week ago). We thought we would actively start TTC from around October/November, but decided not to use any contraception on our honeymoon (I mean, who gets pregnant in the first month right??) Well guess what, this morning I got a BFP!!! We are obviously very excited and happy 😊, but I do kinda feel like the whole day I've been about one second away from a full-blown panic attack! I guess/hope it's normal to be in a bit of shock in the beginning!! Anyone else felt the same initially?
