Hello everyone! I am due to start my period in 4 days and woke up today to outrageous dizziness that has lasted about 4 hours now.  My breasts have been sore for over a week and it's hard for me to lay on my stomach. I had, what I thought was a full period last month and wasn't pregnant. I woke up sweating twice last night as well. Could I be pregnant? Any advice would be greatly appreciated! Thank you!!
