Need opinions please

I’m 14 weeks and 4 days, I’m used to laying down all day everyday. Occasionally getting up when needing something. I was messing around and put in an application, well to my surprise they replied fast. Would it cause any complications with my baby to abruptly start being on my feet all day ? I’ve had no complications with this pregnancy and my baby has a very strong heartbeat. Ive lost three in 7 months, not willing to let this one go too. Thank you guys :)
