Late period. (Odd symptoms)

Nikkea

Hi all, so I was meant to get my period yesterday/today and still no sign, I’ve been getting cramping in my lower belly/back like it’s coming but no period. nipples are brown and boobs are sore, getting really tired but then being unable to sleep, about a week ago I felt as if my stomach muscles were stretching out ways quite fast and also have had sore stomach muscles on and off since, I’ve experienced dirrahea. And also lots of clear watery discharge with sometimes being a light brown tinge, sorry if TMI but just looking for advice. Thanks in advance x
