Pregnancy after miscarriage

giorgia
So I'm about 5 weeks pregnant today. I had a miscarriage at the beginning of June when I was about 5 weeks. I got pregnant again staaight away without even trying, I can't help but worry that the same is going to happen again. 
Has anyone got pregnant starlight after miscarriage and the same happened again or was everything ok?! I haven't had any implantation bleeding but I do keep getting period like pains. I don't know if I'm just worrying too much but I just can't help it 😔
