Been trying for 8 months now

Buffy

My husband and I have been trying to conceive for 8 months now. I have 2 adult kids. I get my period regularly ever month. I’m healthy, I exercise 3-4 days a week. I do hapkido and ride my bike. I was using the ovulation strips but gave up. It would so high but never a peak. What am I doing wrong? :(

I was sure it happened this time but my period came. It’s very light which is not normal for me, but I’m not pregnant. So any advise?
