I started taking Zarah birth control 7 days ago. About 4 days after starting my first pack I developed an itchy rash on my arm and stomach. Both patches are very small, but very irritating and have gradually been getting worse each day. My face and neck are also very itchy, but luckily no rash is visible. I ve never had an allegeric reaction to any form of the birth control pill until now. Should I stop taking this brand or is this just my body adjusting? I know it is suggested to stick to a birth control for at least 3 months but at this rate of irritation there s no way I will even last another week.
