Desogen and time of the month

I started taking Apri in March of this year...at first everything was pretty much okay...this was the first pill i had been on so wasnt quite sure what to expect. Although, it was only a short while until i started having bad mood swings, i started feeling extremely anxious a lot of the time (i blamed it on school - im a pre-pharmacy major) but it just kept going throughout the summer even when i was out of school. I sometimes get random stomach cramps at any time of the month. This pill has made me so emotional, i just wanna be back to normal. I have 1 more week of this pack and im considering stopping but i really want to find a new pill! Does anyone have any suggestions. PLEASE?!
