Discharge

Okay so I'm 22 weeks pregnant and I've been having discharge, it doesn't smell nasty if anything it has a sweet smell to it it has a light scent to it but idk how to explain it and it's also clear, I rinse off my body every morning and I still get it. Some days it's a lot some days it's a little. Idk what's going on I asked my doctor and she said as long as is doesn't smell bad or have any color to it then I shouldn't worry. But I'm just fed up with having to change panties three times a day. Is there any products that can help mask the smell or anything ?
