We made an offer on a house, the sellers rejected it, then they called us back 3 weeks later…

I wrote the house out of my mind when we made the first offer. We actually made 2, and they rejected both, so I had to move on mentally. Clearly, they’re regretting it since they called us back and told my agent they haven’t received any offers except for ours (has been on the market since October). Now that we have some leverage, we plan to make them another offer - one that’s a little higher than our previous, but still lower than list price. I can’t imagine them not just taking it, right? Has this happened to anyone else?
