Just want some advice

Hey ladies so my partner and I are trying for baby #2 and we tried this last cycle. So I’m 22 days late and I’m testing my ovulation and it’s staying the same I’m also taking a pregnancy test and I see an empty line but I feel super nauseous and sleepy and having craving’s and just kinda confused with what’s going on. Should I go to a ob or I just don’t know what to do. Thank you for reading this and replying
