Any ideas?

So I have a longer cycle (around 38 days and it's not always the most accurate since my first pregnancy) so we are ttc again and my AF was supposed to start on Sunday but then today out of nowhere I started bleeding but only a little like I dont think it would have even filled a pad all day and now it's kinda starting to stop and this is not like my AF at all. Usually she comes full force especially after my pregnancy. Sorry I know its TMI but it's got me confused.
