Been regular (27 day cycle) since I was 13 (I'm 28 now) and had sex on the day the online ovulation calculator indicated plus a few days after that day. I was expecting my period on Monday (the 25th) and had cramps, etc but it didn't come. I took a pregnancy test yesterday morning but it was negative. Just started to bleed a little earlier, any idea if I could still be pregnant? Wondering if maybe ovulation was later than calculater estimated or maybe my period came late and I shouldn't retest....thoughts ?
