16 days past ovulation

16 days past ovulation no AF, I took a pregnancy test. It was negative. I sat on the toilet and cried 😞😞😞..I thought for sure this would be my month since AF didnt show up. I have cramping slight cramping in my uterus and back. My boobs are sore and I have this mild sharp pain on the right side. Maybe I have simply gotten to old to do this now. I have praying and trying for a year now and nothing. Maybe I need to except that menopause is on it's way.
