I think it's time to TTC #3

I was on BC for about 5 years. The past year I noticed weird bleeding and also I had a false positive this month. My doctor told me to stop them. So anyway I was on a Mini pill which if you miss you you start to bleed the next couple of day. Well this didn't happen at all. It's been about 3 weeks now and I did start to bleed for about 3 day. Me and my husband have been having sex like crazy because I have my sex drive back. Just wanted to know if the bleeding I had was my AF? We are to TTC #3 but don't know how to track everything.
