Period came after 9 days late with light bleeding..Is it possible to be pregnant?

[Rahavi]

Hii,
    My last period was on 8 May 2017 and t normal 30 days cycle and had an unprotected sex may be three times in MAY.This month my period due on 8 Jun 2017 but i never get my period but got very mild pain in my lower left abdomen.I thought im going to have my periods and the mild pain continues for 3 days and i thought my period is on my way but never.
     Finally i got bleeding after 9 days on 17 Jun 2017 with cramps hardy for anhour but the flow is not continuous as my normal period.I used pads but hardly few drops of blood in it and i thought if the day passes it gets normal.but i never kept pad for other two days even the bleed doesn't come to my panty liner.whenever i go for bathroom or if i wipe with tissue i have blood on it. My stomach feels like bloating and for the past two weeks i feel hungry and very tired...

Note: I went to vacation for a week.May be that could be the reason for these problems.

Please give your suggestions
