You can soak in the tub or take a nice shower
You might be having an allergic reaction. Use 1% hydroelectric cream twice a day! I know it helped me and I switched my body wash to hypoallergenic just to be safe!
Try sensitive skin "feminine wash" down there.
If ur irritated id avoid scrubbing down there to much with any scented soaps. The most natural thing u can do is get in a bath with some raw apple cider vinegar. Also if the itch continues, see ur OB because I get something called BV with every pregnancy and its pretty common to get. My symptoms were itching and extra white discharge. Didnt have a foul smell like others get. Could be normal as many have said but like i said if it continues id see ur OB to get swab test just in case u do have any type of infection. Take care
Do you think you have a yeast infection? Sounds like you may. Call your doctor as they may prescribe the very convenient Diflucan medication which wipes a yeast infection right out or you can try monostat one day (higher concentration of medicine) over the counter medication. /But it takes two days to work. (as in you'll start to feel better in two days). Vagisil wipes are a relief. Use them until the medication kicks in (although diflucan works really fast). You can even leave them in your panties for a bit. Eat probiotic yogurt too! good luck
