birth control

So, I went off birth control in December, my husband and I discussed it and I wanted to get off of it for the health benefits not necessarily to become pregnant. While there are awesome benefits such as sex drive increase, losing weight and all around knowing my body better , the downside is my period is all over the place. I spot for a week prior to my actual period starting. I wanted to know if this goes away with time or is this something I should expect from now on?
