First time mom - 37 +3 constant pressure

Okay so I’ve been up all night with period like cramping in my uterus and back and my stomach hurts - feels like I have the flu. I have the feeling like I have to constantly poop. Every time I go to the bathroom, there’s nothing there. I haven’t had sharp cramps I can time... it’s more of a dull cramping that is hard to track- it’s just constant. I did a cervix check (obviously I’m no professional) but it felt soft and open. Afterwards, I had some cervical mucus come out. Do y’all think I should call my doctor? Or am I overreacting? Thanks y’all! I tend to wait to go to the doctor until I have to so thought I’d check because I’m not trying to have a home birth.
