Help Please 🙈

So I am currently 17 weeks and 4 days pregnant, due Nov 23rd 🙈 I’ve been feeling a lot of pressure down there since Saturday, and also having period like cramps! I have been getting very worried, my hips were hurting I just couldn’t get comfortable 😔. For the past 2 days I’ve noticed that my bump has gone, I can officially suck my tummy in again and it just looks like fat 😔 the pressure feeling has gone, but I’m still getting period like cramps, they are on both sides, still bearable but very uncomfortable, I’m just getting very worried and anxious now😔 I don’t know if it’s normal or if I should contact my midwife 😔 this is my second pregnancy, my first didn’t make it past 7 weeks 😔 any advice would be very appreciated ❤️
