I'm 39 weeks. Woke last night for a wee, then checked on ds. After bending over him I suddenly had really bad pains in my tummy and back, but only on the left side. I do find some movements like bending over set off bh at times but this was different. Really intense, almost like a very very bad stitch. All down my left side and around to my back. But my bump wasn't tight so don't think it was a contraction, and it lasted for 30 mins. Couldn't sit down as it hurt too much. Ended up waking dh as I was in so much pain I started to worry something was really wrong! Was on the verge of ringing labour ward for advice but it eased and I went back to sleep. Since then have had some back ache and bh - same as usual. Baby moving fine. We had dtd a couple of hours before pain started but no idea if that is relevant.
Any ideas what it could be??
