I've just found out I'm pregnant again after a missed miscarriage in July and I feel petrified that it will happen again, I had light spotting last week which I thought was the start of my period then it stopped had 2 negative tests on Saturday then had 4 positives yesterday and another 2 positives today I'm hoping it may just be implantation bleeding and tested too early on Saturday, I already have 4 children and had bleeding with both of my last 2 babies I'm just really worried that it will be another missed miscarriage, how soon should I make a doctors appointment I think I'm only just 4 weeks any advice would be greatly appreciated
