So scary moment.

Last night while sleeping I woke up choking and gasping for air, I had stopped breathing just randomly. I am 20 years old and have never once had an issue with sleep apnea until last night. Can pregnancy cause this? I know that sounds stupid but it's a genuine question. Im afraid I'm going to hurt my daughter by going a period of time with out breathing. I don't know how long I wasn't breathing for I just know I woke up and I felt like someone had been trying to sofficate me. My husband wasn't home and I couldn't ask him if he has noticed me not breathing at night times and being this is the first time it's happened I'd feel stupid if I'd mention this to my midwife and it comes out to be nothing. What do you ladies think I should do?
