Feeling Frustrated

Hi All- Im new to the App was using another & we have been TTC for 15 months. Im 33 turning 34 in June. Weve been using an OPK for 3-4 months now and even went to a fertility apecialist back in Oct '14. Luckily we checked out and were diagnosed with "undiagnosed infertilty" which is wonderful but frustrating. I started accupuncture im February and have noticed some improvements. Back in August '14 my younger sister told me she was pregnant. She had gotten engaged in July '14. It was a hard year. Im feeling frustatted why this is taking so long. Im wondering if we can do anything didferent. We BD every oyher day before I ovulate. Any suggestions? Baby dust to all ✨💫✨
