Ok I'm sure it's all in my head and what not lol but how soon before ur missed period can u get symptoms if any at all??? I'm 8 days away from the dreaded period and the past 4 days I've had nausea throughout the day off and on but it's worse when I wake up and when I go to bed. I also have heartburn.. now I have heartburn regular but it goes away when I take my meds. This hasn't and I've been eating tums like candy. Lol that can't be good. And omg all I wanna do is sleep sleep sleep lol so please someone help me if you can...
