Irregular period?

My baby girl is 9 months old and is eating solid foods + pumped milk. I’ve always been a just enough or low producer and have only been able to pump around 15 ounces per day for the last couple months. With lower production, my period came back last month. Now obviously I know cycles can take a while to “go back to normal” when restarting again, but I’m almost a week late and starting to wonder if I’m pregnant. It would be a true miracle if I were bc hubby and I only got it on once in the past month (and he pulled out before finishing) but it does make me wonder... what have your periods been like lately (for those who have gotten it back)? Anyone else irregular? Anyone else preggo again? If it’s not here in a couple days I will take a test but I am just so not ready to be pregnant again 😫
