A bit confused?

Hello everyone.

Im not sure whats going on but.

I have had really bad nausea, back pain, loss of sleep, head aches, loss of appetite, mood changes.

I have noticed that my areolas will get really big and dark and then go down the next day and so on. My nails are growing really fast and im having to shave my legs every 2 days which is very unusual for me.

I have recently had a cold.

I took a test last week and it was negative. I have been having really bad cramps. Im not sure when my last period was. 😢 any advice on what this could be?
