My OB suggest not to have them in the first trimester but I kno plenty of people who kept them on the whole pregnancy. I did get mine removed and kept them off and my nails are stronger and longer than ever cuz of the prenatal vitamins.
I have acrylic nails too. I'm 31 weeks and doing great! ;)
Just make sure your salon has good ventilation and it doesn't smell too strong when you go. Other than that enjoy!
You mght find that due to hormones and prenatal vitamins your nails grow faster so the fill ins become more frequent.
Your fine and can get fill-ins with no problem.
No your perfectly fine I had acrylic nails with my first and I'm on my second 36 weeks and I have gels.
