Hay, that itching can be frustrating talaga, lalo na when you're trying to follow your doctor's orders! A few of us have experienced different reactions to vaginal meds, one of my mum friends got irritation din from a similar progesterone insert, pero sa kanya naman it settled after a few days once her body adjusted. Since you're getting itching every time though, definitely worth mentioning to your OB kasi baka need lang ng adjustment, either sa dosage, frequency, o pwede ring try ng ibang brand or formulation na mas gentle sa'yo. Don't just push through it, mama, you deserve to feel comfortable while taking care of your pregnancy!
