To much info ?

I know this is to much but ive been wanting to ask this since I've been 5 months in now 8 months but I have a lot of discharge to were sometime it leaves a sour smell on my underwear and I hate it . Even when I wear leggings or something I feel like I can smell it . I never had such thing before I got pregnant idk if it's a pregnancy thing but it's very uncomfortable 😣
