IVF Successful -Today yellowish discharge

Hi. I had my first <a href="https://glowing.com/glow-fertility-program">IVF</a>, implant on the 13th of Feb. Took the beta hcg blood test on 22nd Feb and it was successful. Today I am experiencing some cramps (not that painful) and saw some (not a lot) yellow..ish discharge. Anyone else experienced this? Is this a bad sign? Should I contact my doctor? I am really panicking 🥺
