Pissy mood symptoms and conditions

Have any of you suffered from really bad constipation whilst on Yasmin ???. Im at home now and i look five months pregnant. I keep taking senna tablets but it just isnt working. I eat really healthily drink loads of water. The only thing i can put it down to is Yasmin but im not sure if its just me if noone else has had it on Yasmin. Also have the following:

*melasma on top lip that looks like a moustache.
*cant stop eating constantly.
*really dry mouth, constantly thirsty.
*anxiety.
*feel down on myself

I can only take Dianette as a alternative but put weight on easily on it so im not sure what to do. Did any of you end up putting weight on on Yasmin after the first six months? . I don't know what to do.

Please could you let me know if you had constipation on Yasmin so i now if it is the Yasmin or not. My doctor knows but didn't seem too concerned.
