Fertility Check

Im 33 and i’m TTC for 5 months. This is my 6th month TTC. Having constant postive opk, sustained bbt shift to determine ovulation has occured, normal length of LP 15-16days, period cycle has always been normal and predicted 29-30days, changed my diet, exercise few times a week, having sex every other day and everyday on my most fertile window. What else i need to get it done or should I see a Gynae to check on me? Im abit impatient and frustrated now. Any help?
