So confused

So my last cycle was only 22 days long which means I could've ovulated a lot earlier then what my app is saying. I had some dark brown spotting for a few days right in the middle of this cycleand didnt really think anything of it when it was going on. We only BD'd one day during this cycle cause I ended up getting the flu and being sick the last two weeks. According to a 22 day cycle it says its possible I ovulated on the 8th-10th day and that's the day we BD'd also. Is it even a possibility that I could be pregnant? Im supposed to start my cycle tomorrow according to my app so I will take a test and see but does anyone think its actually possible? I noticed a lot of CM tonight also and that doesnt happen right before I'm gonna start my cycle either so its weird and I'm just really confused now that I'm thinking about it abd looking back at the last couple weeks. Please help if you can or give insight if you have any. Thank you in advance!
