Smelly vagina 😰

So I'm a clean person I'll shower on a morning and evening but ever since falling pregnant my vagina smells really bad but it's sometimes so strong I can smell it through my trousers I'm wearing. It smells like fish. Now obviously this is really embarrassing and I've been to the doctors who did a urine sample and there's no infection or anything. Can someone else please tell me they're going through the same thing and it's not just me and if so how you get rid of the smell. X
