Likelihood of pregnancy 🤰🏼

I'm almost 7 months PP. I got on birth control pills at my 6 week checkup but ended up having to stop them because I was so nauseous all the time. Well I decided to switch back to Nuva ring ( I used this several years before). I was advised to wait till I had my first period. It took about 6 weeks after that for af to appear. I started Nuva ring the 5th day. We had unprotected sex a few times about a week later. I was just curious what the chances are that I could be pregnant? I have been feeling really off lately but I have been stressed as well. I've gotten hot flashes, mood swings, lots of acne,random nausea, and now tingly breasts. I haven't even attempted to test because I feel kinda silly and me n SO have been fighting a lot. He's going on a vacation soon and think I might test when he's gone. What are the chances I actually could be pregnant? Has anyone else had something similar? Feeling kinda lost.
