I only get my period for 2 to 3 days! There still weird on my birth control but not as weird as it was off it would be at the beginning of the month and than the end and the middle than the end! Some months I miss and some months I don't and even missed it for 5 whole months! How infertile am I?

Andy, we can't predict if your are infertile or not. You would have to see a doctor about this.

Have you tried taking the birth control pill to regulate your periods?

Well the birth control Im on makes my period come when the placebos hit but still when I hit the white pills I while either get it on the first pill or the 3rd pill! And still very light and short!
I see the opt clinic in October for my yearly check up I will find it up then I guess

There are many tests that need to be run to determine infertility. You will need blood tests, hormonal workups, etc. We cannot do that over the internet, and I doubt very many opt clinics go into such detail with lab work. Your best bet is to make an appointment with an OB/GYN to get the answers you are searching for.
