Frequent urination

Hi guys I’m Leah I am 21 years old and new to this :) I have a 9 month old son named keaton and he is the best thing that’s ever happened to me ❤️

Anyway I’ve noticed for a couple of days now that I have been urinating frequently and I’m not due for my period until tomorrow. I have been cramping a bit and have been getting sore breasts and dizziness which is unusual for me to get dizzy before my period, I am more tired than ever so I was wondering if anyone has had this before getting their period? I’m hoping I’m not pregnant at this stage as it is hard enough to look after my first child

Thanks 😊
