lacy • Im 20 years old. Baby #2 comming soon
I was just wondering of this is normal, I'll be going to dr. Tomorrow tho. Last night I had like a hot flash that turned into a huge migraine , we went to walmart today to buy some food and it happend again I felt dizzy and horribly sick. So I went to bed when we got home, I still feel like I am burning up and still have a huge migraine , is this normal this is my first kid and I'm 17 , so sorry to bother anyone. I honestly don't have anyone to ask about things like this. I asked Google but no sertain awnser. Thank you ahead of time
