Question about Yasmin..

I have been on yasmin for about 5 weeks now.. and im a bit concerned and want to make sure what i am experiencing is "normal". So when i first started i didn't notice anything different, then a week before i was due for my first period while on the pill my PMS symptoms were really strong i was very nauseas, really bad cramping and my boobs felt like bricks and were really tender. Then i had my period and usually the PMS symptoms disappear as soon as i start but its been 1.5 weeks and my boobs are still swollen and very tender, also i am noticing some blue veins on my boobs.. ive never ever had these veins so im freaking out and also when i press down on them they are hard.. just wondering if this sounds normal at all??

Any advice is greatly appreciated :)
