Rude NP at Doctor visit & kind of losing hope was he right? 😭

So me and my husband have been TTC over a year now and I'm about to be 30. About a year ago my doctor's nurse practitioner told me that basically I'm too fat to have anymore kids my blood pressure was too high (I was sick and in pain that day which raises blood pressure) and they would be abnormal and I needed medication and to exercise more and stop eating so much and no fatty food, like he knows my life 😑 I eat fairly healthy I go to the gym and walk daily at work up to 4 or more hours a day I take vitamins and drink mostly water and herbal teas. Also I've lost about 25 pounds. I'm not sure what it doing on my OB says that everything is fine down there my husband is starting to think it's him. What should we do? We're considering fertility testing on the both of us.
