I am 21 years old and am currently using Ortho Cyclen. I have just been switched to this in July from Alesse and I am a perfect user. For the last two months I have been experiencing abnormal symptoms. Two weeks before last months period I experience frequent urination with a foul smell and abdominal inflammation around my belly button area with pain on the right side under my ribs then I received my period on the exact day it always comes and it lasted the same amount of time but it was a little lighter than previous. This month the frequency of urination continued on and off but with out the smell. I received my period this month yesterday the exact day and time it always comes with cramps like usual; however it started off brown and turned blood red not until later last evening? I'm so confused can someone please help me wth an explanation of this!!?!?

Thank you so much
