What should I do? Will I go to hell?

After a horrible divorce, I decided to travel to my grandmother's homeland in Italy. Although I was raised Catholic, I would say I am agnostic. I didn't really have a plan for my visit, just hopped on a plane, then took the first bus to anywhere. I ended up in a small town. It was late and I found a small hotel with a restaurant. I checked in and went to eat. Maybe it was the season, but only one man sat...sitting near the fire. Anyhow, he ended up being a priest. I told him my troubles and my disbelief in God. He spent the evening convincing me there is a God as we ate. We ordered tiramisu and a bottle of lemoncello. As the night progressed, I realized we were both intoxicated and one thing led to another...your imagination. When I woke up the next morning he was gone, but left a bible on my pillow. When I asked the inn keeper about him, they insisted I dined alone. The thing is, I am now 6 months pregnant. I also returned to the Catholic faith. What should I do?
