The 27-year-old, who plays Debbie Dingle in the ITV soap, said she is feeling better than she did during her first pregnancy with son Buster, now five. But she is suffering from one uncomfortable "side effect" that is causing her problems.
"I'm not quite as tired and the sickness went a lot quicker but it's just the heartburn," she told OK! Online at the Inside Soap Awards.
"I can't get rid of that. That's the only thing now that's making it a bit of a drag."
The soon to be mum-of-two, whose due date is in December, said she was "looking forward to giving birth".
Although she's currently working, Webb said she wanted her character to exit the soap quietly when she starts her maternity leave.
She added: "I'm still yet to have a meeting and talk about it but I'm not sure... it will be really nice just to slide out of the back door but we'll see."
Webb announced her and co-star Matthew Wolfenden (aka David Metcalfe) were expecting their second child together in June 2015.
She uploaded a black and white photo with Buster behind a sign that said "Only child expiring Dec 2015".
In August 2015, Wolfenden and Webb said the pregnancy had given them a stronger bond as a couple.
Wolfenden told OK!: "Having a child changes the dynamic of your relationship, but in a nice way. You have to become a team, which is a lovely thing."
