congratulations on yr pregnancy! I think it's normal to have lower back pain & also pain on yr legs. I have them too and I'm about the same weeks preg as you 😅 although this is my 2nd preg , I kinda feel more tired easily and my calves get sore often. get yr spouse to massage you to relieve some muscle tension! hang on there mummy, we can go through this!! ♥️♥️
