accidentally peeing when vomiting or sneezing

I'm around 13 weeks now... Since the start of morning sickness, everytime I vomit I would leak some pee. It's so frustrating because sometimes I vomit a few times a day and I end up having to change my shorts and undies so many times!!!! (I use a pantyliner and still...) It's not alot but it's so annoying especially when I'm outside... Sneezing is safe 95% of the time but there's this one or two times too. Vomiting is the worse. Is anyone having this issue or is there a problem with my bladder ?
