I have been taking a low hormone combined birthcontrol pill (Yaz) for the past two months and have experienced some increase in breast size and no noticeable weight gain. At the end of the month due to bleeding, i am switching to a pill with a higher amount of hormones in the hopes of stopping the breakthrough bleeding. I went on the pill at the age of 16 (practically 17) for the purpose of clearing up my acne and to regulate my period which I was getting about every 52 days (very irregular). I am curious, will this switch to a higher dose of hormones cause my breasts to grow? The women in my family all have about a large C while I have 34B’s. Thanks
