New and confused!

Alex
So my husband and I have been trying and I track everything and what not. The first week of trying I started getting moody and tired and sensitive to smells... I tested and it was negative. In my mind it's to early to tell  and really early for symptoms I would think. But it's been a few more weeks and I'm 7 days past ovulation and my nipples are sensitive and I get cramping and some discharge.. I tested yesterday at my 6 dpo and it was negative ... Am I testing to early? Would I be feeling these things at this point in time? I feel a little crazy honestly !!!
