Please help.. conceiving nightmare😩

I need advise...

So my and my SO have been trying for approx 15 months now and have had not one bit of luck.

I have never been pregnant nor has he ever got someone pregnant so we’re beginning to worry. I saw a doctor last week and I’m waiting for a letter from the hospital.

I guess my questions are how long did it take you all to conceive?

Had you been pregnant before?

Were you concerned?

What were the outcomes? (Diagnosis wise)

Did you take anything (vitamins etc) which helped you conceive?

I feel like I’m asking for a million things but I really am at a loss at the minute and honestly any advise and help will be so appreciated❣️
