Pregnant?

Hey ladies! TTC for 4months now and I am now 13 DPO cycle day 31! My cycles have been about 30 days lately and Glow is saying AF due March 1. I've been having creamy white CM and today my man and I had sex and there was reddish color with the white CM. Been really tired and cranky past few days and get upset stomach a lot after I eat. Trying two wait until Sunday to test, don't want another negative :( if you have have any similar symptoms or advice if appreciate it!
