Birt symptoms and conditions

I started taking Yasmin this past sunday, so far, so good...reading all these posts worry the crap out of me...i'm only really on this because i have really BAD pms, which people i know including my boyfriend thought it could be PMDD because how "crazy" i'd get, bad cramps and my period sometimes likes to show up almost whenever even when i track it....i'm a moody person already and so far i feel pretty good, pretty stable which is nice, i guess the only complaint is that i'm kinda constipated and i'm exhausted, but i'm unsure if this has anything to do with this pill or not. i travel constantly and eat bad food since i'm away at college so sometimes i have some issues....oh my sex drive is usually pretty fine, i haven't noticed anything there yet, i still think about doing things and want to...so, my question is what should i do? shall i continue to use it and see what happens, or should i stop it or get a different pill?? i go to therapy and i am also making sure that my boyfriend and immediate friends notice if i act a little stranger than usual....
and i was on a different pill back when i was 15 and i don't remember much of it besides i don't think i had any side effects so i've had a little experience with birth control before...
