Pregnancy possibilities at 5 weeks postpartum

What are the chances? I haven't had a postpartum period yet but I'm having signs of ovulation. My cervical mucus is so thick that it won't break or separate. I'm getting aversions again to angel hair spaghetti and sauce. Breast are getting sore again( not breastfeeding) and my mood swings are up and down a lot lately in the past couple days. I don't know if this is the hormones getting back in balance, I didn't experience these things with my daughters postpartum. Anything is helpful. And I know I was stupid for having sex before the 6 week checkup. I've had it twice now.
