Pregnancy but negative test

Hello everyone!

Im new, so I might as well introduce myself. Im 24 and my husband and I wanted to try for baby.

On november 3rd I had my period and after that I got this light spotting on 19th and i thought i really was pregnant so i did many home pregnancy test and they were all negative.

Than my period was late for about 10-12 days, i went to a doctor. She said she saw the baby and just to be sure she told me to get hcg blood test. It was negative too. I was devastated.

This month, after having my period on 16th we calculated my ovulation days and tried to get a baby in the oven.

Im having cramps on my left side from time to time, i even have some butt pain (which may be unrelated to pregnancy symptoms) and back pain. I feel tired and sleepy.

The app shows that Im 2w4d pregnant now(hopefully) but i topk a test and it was clear negative. I dont want to get my hopes up but do you think i might still be pregnant?
