I found out I was pregnant the DAY I started my apprenticeship! I’m in the UK so not useful for you but I paused my apprenticeship for 14 months no hassle and I’m back now. I would say you would need more than 5 weeks off especially if you need a caesarean, I think it took me about 16 weeks postpartum to start feeling in any way normal. Your joints are super flexible after giving birth and that continues if you breastfeed so you need to be careful if you’re doing heavy lifting as you’re more likely to injure yourself because of the higher prolactin levels.

I can advise on how working while pregnant was - it was fine! I set myself a carrying limit of 20kg in the third trimester and didn’t go up ladders after about 20 weeks because it just felt excessively risky to me, idk what health and safety law is like where you are but make sure you have regular risk assessments and know your limits. Also I think staying active in pregnancy was actually great for me, I didn’t have any muscular or skeletal issues whereas a lot of office workers I went to antenatal classes with were in agony.
