So my husband and i have been trying to have a baby for about 7 years but this is the first time i decide to track myself. So here is my question i have been having this pain in my stomach for the last 2 weeks and every morning im so dizzy i cant even stand up and so nausea but its only in the morning because i can eat everything without vomiting.. My period is suppose to come on the 13th but i have no sign of it coming what does everyone think....
