im 21 and have been off the pill since sep 2014 . i have been with my partner for 3 and a 1/2yrs, we are 100% loyal to each other and we have sex about 3/4 times a week. since coming off my pill i havent gone back to a normal cycle and have noticed the longest gap i have had between each period is about 8days and i mean full on periods. i have been to the doctor and had scans done and all has come back clear. any advice on what it might be and am i going to be able to get pregnant with my period like this.

any adive will do thank you :)
