Achey bump!?

[PassTheAfterEights]

21 weeks preg w DC1 and - having been pretty much very comfortable since the end of first trimester - have quite an achey bump today. It's not cramping and doesn't feel 'internal' - more like the round ligament pain I had a few weeks ago when things were just starting to stretch a little. I think it feels most like a pulled muscle. Feels very full in there, skin's tight, breathing in deep so my chest expands makes it stronger.

Is this normal? Bump is quite pronounced now - like it's definitely there, no sucking in for a flat tum - is it just muscles/skin under pressure? (will using more bio oil help?)?

Thanks in advance for any experience!

You might have pelvic girdle pain. Bump feeling stretched/stitch like pain was how mine started. I'd mention it to your midwife as it took 5 weeks for me to get a referral for physio and by that point I was in quite a lot of pain.

Thanks so much for response @InfantaSybilla will do - had what I thought was sciatica on and off on both sides for a few days, also apparently more likely PGP, so that would make sense. Apparently there is a free pre-natal group physio locally so will get on with that too. Thanks again!!
