Hi. I have had no physical issues so far that I have noticed (at 15 weeks), other than the fact that my scans are useless. At 10 weeks, my harmony scan had to be done transvaginally. My 12 week dating scan was useless for dating (partly because the baby was hiding, but the tilt definitely made it so much harder, and the sonographer gave up.) I'm back on Friday for another attempt at dating, and I'm just dreading it completely.
I have one, I have a child already but only found out recently after a mmc, made it through a whole pregnancy with no idea! It does explain my labour though - it was all in my back and I never felt what I expected contractions to feel like. Didn't get to hospital until quite late as I couldn't time contractions properly!
Haha, it's only my experience, it might be different for you! And it was definitely painful, but I had a TENS machine, and it was actually a really good labour - 12 hours in total, didn't go to hospital until I was 8cm, only gas and air once I got there. I'm hoping I have similar this time!
