What's going on here?

🦖Meg🦕 • It’s time, I am ready. After several miscarriages, one ectopic & finally one pregnancy that made it to term. We have waited a few years before even thinking about it. Now We are ready! TTC for #2.
So my hubby and I work odd shifts he works all day and I work afternoon night. Sex is sometimes hard to get to when you work odd shifts but my hubby is a frisky morning guy and I'm the frisky night girl. Out of nowhere at 2 am he was frisky and determined. This is unusual for him. I had some cramping after I was supposed to ovulate. And I've been told demon give off pheromones around ovulation. Could that be what that was all about? It just struck me as out of the ordinary. Any ideas?
