I was actually in a similar situation. I got pregnant right after nursing school
(like literally 2 weeks after finishing) and by the time I started working as an RN I was already 5 months pregnant. Between new hire orientation and the didactic part of training, I was only able to work on the floor for about 6 weeks before going on maternity leave. I didn't return to work until almost 9 months later and I'm at a new facility, in a new specialty.
It has definitely been tough adjusting to being back to work but it's doable. I would advise you to watch some videos (YouTube) of basic nursing skills like Foley catheter insertion, spiking bags, priming lines, etc. Also just be open to what ever happens. Be patient and try not to be too hard on yourself. Everything will come back to you eventually as you get into a groove.
I definitely have those days where I start to question if I am cut out to do this but they are happening less and less as time goes on. I've been back to work for 2 months now.
For me, the hardest part is leaving my daughter each morning, lol. I have confidence that you will be fine. Don't be afraid to ask for help. Good luck!
