Just looking for some advice ...

My husband and I have been TTC for about a year now. We had a miscarriage back in January and have been tracking ovulation and bbt but still no luck ... I am 27 years old soon to be 28 and my husband is 33 turning 34. I’m just wondering when/if I should consider going to see an infertility specialist to see if there is any cause for concern?

Thanks in advance for your thoughts on this!!
