Confusing symptoms

Malika

If someone could help me understand my body I’d be very greatful.

I had my period last week, if that’s what you want to call it.. it was brown, very light and lasted 2-3 days. I took naproxen at the same time for 2 days so I assumed it was because of this.

Last 2-3 days I’ve had bad diarrhoea, very mild sore boobs and achy legs and a bit of cm. Too scared to test because I really can’t deal with another bfn.. 😫😫😫
