Help!!! I'm so confused!


So AF is due tomorrow. I don't have any symptoms or signs that it's going to start which I normally do. I took a test at 7dpo and 10dpo and they were both negative. I've been nauseous and having dizzy spells for a week now, some mild cramping and lower back pains, my breasts have felt full and sore off and on. I don't want to stress about it but I think I am and at a lost as to what to do at this point and I'm an impatient person. Any thoughts?? I'm so new to this and I don't if I ovulated when Glow predicated and I've never used OPK kits before.
