Feeling very ill and worried

Jenn

36 weeks pregnant and since this morning have been having non stop liquid BM. Anytime I eat anything or even drink just water. My stomach has hurt and cramped so badly all day, very gurgly. So much pain, can barely do anything but lay around. Yesterday was full on exhaustion and headaches.

Stomach flu?

Covid 19?

Pregnancy related?

When should I worry?

The very last place that I want to go right now is the hospital obviously
