So I know it's a little early but I'm 4DPO today, ever since the second day I have had mild cramps, severe fatigue except for bedtime then I can't fall asleep, and been nauseous here and there; today has been worse, the cramps are the same but I'm more nauseous, add hip pain, lower back pain and constipation (sorry tmi) but I'm not sure if I'm just getting my hopes up and it's in my head or if anyone else went through the same thing and got a BFP?
