Need advice could I be pregnant?

Natalie • Lost our baby 1/22/18 👼🏼😭 Rainbow babygirl 12/14/20💜🥰 Babygirl 12/1/21 Trying for our rainbow #3 🤞🏼🥺 after mmc

Since my mmc my cycles have been ranging from 25-26 cycle days. I ovulated this cycle on cd 14 and had this bleeding yesterday 11 dpo around noon and now more since yesterday now and I’m now on cd 26. I’ll be 12 dpo tomorrow . I’ve been taking pregnancy test still showing negative. I felt really really nauseous this morning, had a headache also, had pinching feeling in lower abdominal.
