Confused

Ok so I been trying to get pregnant for many years and as of last year I started question my doctor about why I haven't been able to get pregnant. Well he told me they couldn't find any thing wrong and I should keep trying. So it's been a couple months and yes we been trying so last month kinda got wried for me exactly 7days after my ovulation I started spotting nothing more just four days of spotting and I'm normally irregular in my menstrual and pretty much always bleed heavy. So today makes it 10days late for my cycle and I'm wondering if I should count the spotting as a cycle or something else. Don't wanna get my hopes up for nothing just wondering if I should get worried.
