I'm so gutted 😢

Angela • 44 yr old Mother of 3 older children to previous marriage & a 4 year old boy to my partner of 5 yrs, ttc no 5 for 2 years, did fall pregnant last year in June but lost the baby at 12 weeks. Now Just had my baby boy Heath William 13/03/20 😍

Had 2 positive results with clear blue 2 days ago, took a test today with first response & negative 😢 was due for af yesterday & I know I ovulated 10 sept because took a pos test so my period should be here? So confused
