I am 21 weeks pregnant and every time my husband and I have sex, about a day or so later I get extremely itchy around the hairline on my labia . It doesn t really feel like a yeast infection . My vaginal area feels fine and I haven t noticed anything other than the normal discharge . Sometimes I will feel little bumps where I itch. I used a mirror to look and the bumps look like a slightly darker pink than the surrounding area.
