Confuseddd!!

I was due for af on the 22nd but she didn't show, I had a little bit of bleeding on the 25th and 26th but just had brown and pink spotting since, I didn't get any of my usual af symptoms I just kept feeling really sick and taking 4 hour naps everyday from about a week before she was due till now, on Sunday night I had diahorrea and felt really sick and couldn't sleep and since then keep getting hot flashes, also got stretchy cm today, anyone else had this or know what it could be? Just not been feeling myself since :(
