Strange Symptom

So a new symptom I am having this week is gasping. It may sound weird but for no reason as I am going about my normal business I'll just involuntarily gasp like I don't have enough air just once and then go back to breathing normally. It is so strange. It's been happening a handful of times a day since I hit 12 weeks. I didn't remember this off the top of my head but I mentioned this to my mom and she reminded me that I had this same thing around this time with Gabriel. After she told me I did remember it. It's nothing big just kind of weird!
