Faint positive 3 days late after stopping pill?

Hi,
I have been on the pill for 8ish months after having my baby boy last year. I came off the pill 2 months ago and had a period approx a 29 day cycle. This is my second month off pill and we thought we would try for another baby. AF didn't show up on time and took a test which was negative. I'm now 3 days late and took another test today which was a very faint positive. I don't know whether to get excited as I've heard late implantation can cause early miscarriages. Do you think it's possible I ovulated late because of coming off the pill? Was looking for similar positive stories? I don't want to get excited as had 2 miscarriages in the past and don't want to go through it all again 😟
Thanks xxx
