A month and a half later ...

So I got off of birth control on June 18th. That was the last day of my period. Still haven't had my period. I know it takes time for my body to adjust after being on the pill and all. And I took a test a week after my period was late and it was negative. I'm just tired of getting my hopes up. Is my body still adjusting or is there a possible chance I could be pregnant? My fiancé and I have been trying ever since I got off the pill. At least every other night. Opinions?
