I left work partly due to mine, it was so uncomfortable and I couldn't get anything done at work because it felt like my skin was going to burst open. Found it very hard to take breaks.
I have slightly high BP but midwife wasn't concerned about swelling as no protein in my wee. I panicked because the internet told me if it pitted (ie, you press on it and the imprint stays) then it's the wrong type of swelling and you must be seen. Again, midwife seemed non-plussed.
So in conclusion, as long as you are under regular midwife care and you let them know if it comes on very suddenly or severely, and get them to have a look at each appointment, I think it's fairly normal, even with a good BP!
I won't lie, mine still freaks me out when it gets really uncomfortable though.
Get those feet up throughout the day, it makes a world of difference.
If you can get someone to rub the fluid away, even better!
