So I'm now officially 3 days late for my period ... My husband & I had sex Feb 1st-3rd, 5th & 7th all unprotected... My ovulation window was Jan 30th-Feb 5th ... I took a pregnancy test Sunday, but I dropped in the toilet before using it.. However I still used it, & it was positive, very faint line (picture below).. I figured it was inaccurate tho.. This evening after dinner my husband & I went to get tests. I used two different test & they both were negative... I've been a day or two off but never 3.. & my menstrual is never the exact same day every month but it's been a pattern of 26,28,27,26,28,27.. & my period always last 4/5 days.. No more or less!
