So Worried :(

Hi. Im 30 year old and trying to conceive for 6 months for baby #1 but no success. I have been using opk to track ovulation and it does show high and peak fertility so i presume i am ovulating. I do get periods every month, normal flow.

I am so much worried now after this 6th cycle :( what should i do?? Should i see a doctor or still wait? And how long to wait?Clock is ticking and Im scared and worried.

Since i was using opk from start i thought i should have gotten pregnant faster.

Any comments of ladies who taken a little more than 6 months would help.
