It's pretty normal for a cycle to be a bit heavy after not having one for a while- but given emotionally where you are, I'd encourage you not to hesitate putting in a phone call to your doctor- just let them know you stopped taking the pill and need a little reassurance on what is normal. They are there to help!
I'm sure this isn't anything you want to hear, but just remember it takes time to emotionally, mentally, and physically heal from what you have been through- know that you are not alone!
