Words of encouragement.. ? TIA

Got a BPN today again. It's also my husband's birthday today and I was hoping to surprise him. We've been trying for almost a year and have had 1 miscarriage. Today o still feel guilty for the miscarriage because I didn't know I was pregnant and I felt like I didn't take care of myself well enough, like eating more healthy/prenatal exercise. (FYI: No drugs were used). All my friends and families are either expecting or already have kids. And to add on top, months after month BFN, I just feel so.... ='( any words of encouragement or tips from successful pregnancy will be strongly appreciated. Thank you in advance.
