Advice I went into premature Labor with my son who is 15yes

Nacy
 I was on bed rest and stayed in the hospital for a month. I was 3 cinameter dialated and had to be put on med to stop the labor. So now I've been TTC and I was wondering should I seek  medical advice now or wait until I'm pregnant.. BTW my medical copays are high so I go to the Doctors when it's a most. Has anyone been through something like this ?
