My husband and i are ttc and after 6 months of no succes, should we worry or should try other methods what can help us?

Don't worry too much: If you're 27 with regular cycles and a clean health history for both of you, it's not very worrying. At this point you could use an ovulation predictor kit (opk) to time intercourse. If you're irregular, have a history of endometriosis, stds such as chlamydia, or surgery such as a burst appendix, see a fertility specialist (rei) for help now, otherwise you can try for 12 months before seeing a rei.
