advice wanted

Mel • I have three beautiful boys... Justin 8 Reggie 2 Rudy 1 And now trying for number 4! Hopefully a pink one haha xx
I'm 34+3 and I've woken up with a strange feeling. Every step I take I get this very heavy feeling and sharp pain in the top of my fanny. Any thoughts? Second baby. First was born at 32+4 spontaneous labour x
