Ovulating? Pregnant? Idk!

Too early to test.. My period ended January 17th and it was basically just spotting which isn't normal for me. I have been having these symptoms since the beginning of this month.. (nausea, super bloated, heartburn, sore breasts, itchy nipples, fatigue, but takes forever to fall asleep, increased appetite) and now I have a pinching/pulling cramp in my uterus and to the right side of my ovary. All my hpts have been bfns and I even got a blood test on January 9th because AF was 13 days late and it was negative. I'm just losing my freaking mind.
