K.S.
That is very normal. I am going through the same thing right now. I just had a baby about 6 months ago. I have been on BC for about 7 years on and off. My Dr told me that it is very normal to have heavy long periods because you are not on the pill or anything. The BC actually controlls your period. If you are not on any form of BC then your period is trying to regulate itself. I have an IUD but it has no hormones in it. I sometimes have 13 day periods and a week later have a 4-5 day one. It is starting to get a bit more normal the longer I am off of BC. I would not worry and just use extra protection. You may have to use tampons with a pad too. That is what I have to do. I dont have many clothes changes anymore. Good luck concieving. Your body is just getting used to not having any hormones. It will be fine. I hated my IUD becasue of the periods too. I am getting used to it now. Good luck again.
