Hi Ladies!

Just looking for some guidance. My husband and I just started TTC last month. Now I know it does not always happen this fast! However, I have been feeling totally off this past week: nauseous morning and night, inability to eat certain foods, and headaches. My next period is due in 4 days and I continue to have negative HPTs. I know there is a possibility I may not be pregnant and my body is just preparing for my cycle. I was just curious if this has happened to anyone and then got a + HPT later on? Thanks!
