Could I get pregnant ?

I’ve never tried to have a baby but if it ever happened I would feel blessed and happy about the situation. Im not going to lie there has been times the past few months where I really thought I would be pregnant (my S/O and I have a lot of sex and we never use protection) and it just hasnt happened. Does anyone think I could get pregnant this month (ignore the yellow pill symbols I just use the reminder on the app) knowing sperm lives inside 3-5 days or would I need to have sex on a certain day do you think ???
