Preterm labour at 33 weeks.

Went to the assessment centre (midwife centre to check on baby and if you’re going into labour or have problems) on Tuesday for tightenings and watery discharge. Got released and everything was fine, still had the tightenings on Wednesday and rested all day thinking I had a stomach bug as I was sick and had diarrhoea. Thursday I was totally fine and then today I’m so tired but feeling okay until now. I’m sooo so so so hungry and could eat my body weight in food right now after having breakfast, lunch , tea and snacks😣 I’ve had watery stool 4 times today and I got stomach cramps at around 2pm but not really bad. It’s now 7:45pm and at around 7:20pm I started to get back cramps and now I’ve got a really bad ache in my cervix aswell as pressure and cramps like bad menstrual cramps that don’t seem to let up. I was thinking it’s a pulled muscle but now I’m not sure as I’ve tensed my stomach and it’s not hurt but coughing does. The bottom of my stomach is also a little bit tender. I don’t want to waste my Midwife’s time but at the same time I’m in so much pain I don’t know what to do😭 Any advice? I’ve taken paracetamol.
