if any one can help with this I'd be so grateful

Zoe • 27 years old and engaged to my best friend, my soul mate 💕 1 mmc at 12 weeks and 1 mc at 5 weeks 🌈 my angel babies ✨
So I'm 4 weeks and 1 day pregnant according to glow, I have had to mc in the past so tad nervy ..... today my hips lower back almost like bum and lower tummy just on edges really have been getting like a dull ache sort of feeling, it's not like period cramps - has any one else has this before ? Can any one shed light on what this might be ? Thank you
