Frustrated and i dont know why😭

Hello! This is my first post since i started using glow!

My partner and i have been TTC since September and have had only negatives. This time around my peak ovulation day was the 2nd, we BD all that week. My best friend made me take a hpt yesterday the 8th and obviously negative still. I have been cramping none stop and today i have been super moody/irritable/frustrated and i never feel this way. I am a super easy going happy person and nothing is out of the ordinary to make me feel this way. Please help. I feel like im going crazy😭
