1st miscarriage and trying again

I am going through my 1st miscarriage at 5-6 weeks pregnant. We would love to try again and I hear you are very fertile afterwards and can ovulate as soon as 2 weeks after etc. we have been given the all clear to try again by drs once I get a negative pregnancy test.

I’m just wondering though, I’m seeing on here sadly a lot of women get pregnant straight away again and miscarry again😢

Is this common? I’m desperate to try again and dont really want to wait longer. We already have a 19 month old. But I can’t take the rollercoaster of emotions of getting a positive to lose again.

Is there any successful stories out there???
