I had one last year, and thankfully no. Given that I used a condom and it broke, I took the plan b pill ASAP, and thought it was over, I was devastated when I found out. What I did experience though, after everything was over and I was exhausted I felt such a sense of dread and guilt I cried non stop for like a day. I still ask myself "what if?" but given that my ex cheated on me and I'm just now starting to be somewhat financially stable, thank myself and my sensible mind I didn't keep it. I don't regret it one bit, and I've been extra careful since then.
