What to do ladies

Whenever I was 16 I had my first miscarriage at the time I was dating a total train wreck. I am now 21 and have been married for 2 years, me and my husband has been trying to conceive for 6 months now and no luck. Do I give it more time On trying before going to the doctor? I’m terrified the doc will give me horrible news I’m not fully ready to hear yet. I’m so confused and sometimes get depressed because all my friends and family are having kids and all them are asking when am I going to with my husband and it tears me up. Please some advice 😞
