12dpo with a BFN warm sensation in Uterus

Megan

Maybe someone can help me out with this confusing time.

I’ve had my normal AF symptoms and I’m due tomorrow.

I’ve also been having symptoms that doesn’t ever occur that I know of along with my cycle.

I’m feeling warmer than usual but no fever. Last night felt a warm sensation in my uterus. Like someone shot a IcyHot up there.

My normal AF symptoms are dull back ache and moodiness.

My boobs are not tender or sore as they were never during my AF and other pregnancies.

No spotting. No sore boobs.

So far, headaches, lower back ache, bloat, constipation, recently warm sensation in uterus, some nausea.

Took a pregnancy test today and got a BFN.

What’s my deal? All input is welcome.
