Summers eve can actually through you're whole body chemistry off. I would double check with your doctor, but I had the same thing and it was a yeast infection. Docs recommend the Regular monistat as it is 7 days and yeast infections while pregnant are persistent and the three day monistat just won't cut it
u can use thrush cream while preg very safe to use can get it over the counter
Sounds like thrush just a yeast infection super common in pregnancy you can get a cream to clear it up from your doc.x
Try using summer eves ph wash or wipes you ph balance could be off and can be causeing that.
its not uncommon to get a yeast infection while pregnant I always got cream from the ob not sure if over the counter cream will be safe . is there a nurse line you can call .
Sorry to hear you are having that horrible sensation down there but the best advice please call your doctor or midwife because that is not normal! Hope you feel better soon!!
