Could I be pregnant?

Hi guys! So according to the app I use I ovulated on the 16th. First month of ttc so I don’t know how my cycles are. I felt some pain on the 17th in my lower left abdomen (ovulation?) and had some pinkinh/light brown spotting on the 19th and 20th. Could this have been an ovulation bleeding? If so, could I be pregnant? We BD on the 4th, 5th, 9th, 15th, 17th, 18th. Please help me out, I’m feeling symptoms everywhere while it’s still way to early to know 🤞🏼
