Feeling sick?

So my husband and I have been trying to get pregnant for a short amount of time now. I have never been pregnant before but recently I have been feeling off and having some odd cramping I’m my whole stomach and feeling nauseous. It happens everyday and the same time. I’ve been having hot flashes on and off throughout the day and getting lightheaded. I’m not sure if it’s just me psyching myself out or what. I have some pregnancy tests at home but I’m afraid that if I am pregnant that it would be to early to tell and I would get upset. I’m 5 days away from my next period I’m just so impatient I don’t want to wait.
