Swollen lady bits

ky

Hey ladies I'm 13 weeks pregnant I've been with my husband 5 years no STDs weve only slept with each other as far as I know they test you at my ob office ever since I got pregnant my vagina feels like it swells up and itches sometimes they checked I have no uti or yeast infection i plan on asking about it again but I'm wondering if it could be dues to the extra blood floor my breast have been itchy as they've grown fast to so idk has anyone else dealt with this
