I'm 13 days delayed now... from August 1-31 me and my husband is sexually active because we want to have a 2nd baby... My last LMP is Aug. 31 and i have a regular 31 days cycle. my expected date of period should be sept. 3 on the first day of delayed menstruation had a blood pregnancy test but got a negative result. so i go on with my life thinking that i might just be delayed menstrual period but on sept. 12 i saw a pink discharge when i wipe after i urinate... next morning took a home pregnancy test but still negative result.. whats happening? could i be pregnant or my body just tricking me?
