Does Taking Mini Pill Cause Drowsiness, Thrush And Tiredness?

I've been on the mini pill for about 3 or 4 years as i get aura migraines. I've been on cerazette and another one and am now on the last one to try norgeston. I am constantly tired and at the weekends I can sleep for over 12 hours (I work full time so about 7 hours a night during the week). Also I've been on Norgeston for about 6 months and have had thrush 3 times, I seem to have got it more since being on the mini pill at all.

I have tried to discuss this at the family planning clinic but they did not even listen to the other problems i was having, dismissing me with the thrush thing and insisting nothing like this can be related, it's more likely my husband has cheated and given me an std! (I know this is not the case and have had all the tests recently).

Can the mini pill cause these problems
