Late eve 😳

So my boyfriend and I have been having unprotected sex for a year now. June 04 2016 I was waiting for flow to make her entrance and she failed to show up. 😳 I panicked of course. But I'm irregular so I hoped for it to come soon. It made its appearance on June 14 2016. Lasted my normal painful 3 days..and stopped. I was concerned about that. It came back the following day. So flow stopped on what would be Day 4 and started up again on Day 5 but was normal flow. I paid it no mind. Almost 2wks out from when my cycle ended June 24 it came around AGAIN but a much lighter flow. Assuming my cycle is just out of whack because of the weather or my next cycle was just beginning early. It has happened to me Like I only wore a liner and barely filled that up, which is uncommon.
