I’m Confused 🤨

Lexx • Currently pregnant with my 1st IVF baby expecting May 1st

Hello!! My period comes every 37 days. Well I’m now 12 days late as of today. I’ve tested on Tuesday and it came back negative. I’m waiting to test again this coming Saturday. I feel like Aunt Flo is coming but she doesn’t. I don’t know what to do, I’m hoping to be pregnant but I’m feeling a little discouraged because I’m not having any pregnancy symptoms. I’m all over the place I’m sorry 😞 please respond.
