Ohkay So I have alot of confusion going on.

Im new to trying to track everything. So i have alot og questions. Ive been having body aches every where on and off. ive been so sleepy these past couple weeks even when i nap it isnt good enough. ive been so hungry yet nothing sounds good, ive been having period cramps and yet no period. on my ovia app it said i was supposed to start my period january 4th. that was the app i used to help me get pregnant before. i took a test but it was negative. i have sex almost everyday lol so am i testing too early? i tried checking my cm is its really watery but yet lotion like. i just wanna know if anyone is or has gone through something like this and when would be the best time to test again? thanks in advance baby dust to all you lovely ladies
