Panic attack and belly went hard?


Ok so my period was due 4 days ago, got sore boobs, had cramps.

Last night I had a panic attack, I’ve had a few before but this one was by far the worst.

I was trembling uncontrollably and also my womb went rock hard? It felt like braxton hicks (I’ve got a ds so know what these feel like) and it was hard to touch too!

Any ideas? All tests are negative :/
