I recently switched back to Yasmin from Loestrin 24 fe, and my libido has suddenly vanished. I started to notice mild changes about two weeks ago. I feel bad because I know that my boyfriend has noticed as well. I actually brought it up last night and he said, "Yeah, I thought it was just me..." Also, my breasts have grown almost a whole cup size! I don't want them to grow any larger! It has only been one month.. should I stick it out and see if the side effects even out???
