Need advice…

Hi ladies, I’ve not used this app in a very long time since my other two pregnancies.

I now have a boy who’s 6 and a girl who’s 5 and I’ve just found out I’m pregnant again! Even tho I have done it before I feel clueless to everything… I am currently 4 weeks 5 days pregnant and I’m getting this when I wipe? Is it implantation? I am worried as I’ve had a lot of miscarriages and really don’t want to loose this one..
