I’m so confused please help

I had a miscarriage March of 2023 & have been trying to conceive ever since.. fast forward to this year, my period was due 2/10/25 & it is currently 2/18/2025 & still no period. I have been cramping as if I’m going to get it but haven’t.. I’m feeling discouraged because I took 2 test one on 2/15/2025 & 2/17/2025 & both say negative 💔 spoke with friends & say I could be having a cycle change but I’ve never experience this before EVER .. is there a chance I could be pregnant ? If it’s a cycle change how can you tell?? Do you still get period symptoms when your cycle is changing ??? I’m so confused and loosing hope. I really want my rainbow baby.
