How long after TTC for baby #2 do you seek infertility testing?

We have been ttc baby #2 for 14 months now. I’m 30 and my husband is 34. Should we start to get tested for infertility?

When I had my annual in November my doctor didn’t seem very concerned, since we convinced with our 1st 2 months before trying! (Doctor told me to go off the pill 3 months before trying). At my annual they took my blood to make sure I’m ovulating and the test came back positive. So that’s good.

We had a chemical in August 😞 but, my doctor said that’s a positive sign too that I’m fertile.

After 14 months we are just beginning to worry somethings wrong. I had to have an emergency c-section and my husband is paranoid that something went wrong...

So please flood me with any and all advice and opinions! Thank you ladies!!!
