does any one have irregular periods ????

Kaylee
So I have been recently keeping track or my period because my fiancé & I want a baby so bad. Well I counted out my cycle which was 48 days long! So when I did get my period it was heavier for a day & I had so much blood clots. I've always noticed I was irregular but it gets heavier & heavier the older I get. I am 20 soon to be 21. I met with my obgyn. They ran test on my for hormones std etc & im 100% fine! Is this normal??? ... 
I don't want to take birth control to regulate my cycle when we are trying to have a child soon
