Too many dips, do you think I still have a chance?

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 😍

Also I had sex last night & after I wiped & it was pink? Implantation?
