So got a smiley face on my ovulation test an had sex that day because that’s all I could get he has to leave for work for a couple days an yesterday I got my period! I’m so upset I’m 40 an he’s 51 an nothing ever works an we lost our little one last year it was horrible I was 5 months pregnant😢😢 So if the test was positive for ovulation why didn’t I get pregnant??
