Hmmmm What do you think!!!

So my fiance'and I are not ttc... however we are not preventing it as well... so I got my normal period on 10/10 it lasted 3-4 days instead of the 5 days it normally does, but all in all it was a period!! so 16 days later I got what I thought was another period, it began with light spotting that went into a full period the next day and then became very light to spotting the next 2 days... that lasted for 3-4 days as well... now my cycle is ALWAYS 28 days so I'm confused. I have two children from my previous marriage although I cant remember the early signs I felt.. I have no breast tenderness, but I'm very tired and cant get enough sugar(weird for me) I dont know if I'm pregant... I was scheduled to get my regularly scheduled period Sat nov 7, so I was thinking I would wait until after then to test... any suggestions or simular story... I'm very confused, but none the less I would be excited if we are actually expecting!!
