This is my third pregnancy but I have had two symptoms that have really stuck out to me lately that I didn't have with my first two. In the middle of the night, I wake up with a very dry mouth and I wake up coughing/choking. I also have been experiencing migraines which I usually have hormonal migraines around the time of my period, but never with pregnancy. I am 15 weeks on Tuesday, I will be brining these up to my doctor at my appointment but I was just wondering if anyone else has experienced this and if they have an idea of what's going on.
