[|Human|] Ive recently started taking Yasmin birth control and first of all Ive had my period for the whole month and 2 days ago i started drinking the white pills from the pack so im assuming that that is when my period starts. Secondly my breast have become a bit bigger and they are a bit tender. is all this normal???
[|AI|]  Birth control pills are not supposed to cause any irregularity in bleeding neither the heavy nor prolonged bleeding. In fact, they are supposed to regularize otherwise irregular periods. If with the pills you had continuous bleeding for the whole of the month, it means that either the pills were not taken regularly or they are not suiting you, and you may have to switch to some other dosage combination, may be with higher dose of estrogen in them. Heaviness and tenderness in breasts is known while on birth control pills. It is due to the water retention property of progesterone component. Soon you will be used to the size and the tenderness will not last long. If it is becoming too uncomfortable, you may try restriction on salt intake.
