I missed my period

Two months ago my period came on the 28th of the month. Then last month it skipped and I missed my period altogether. Ever since then I've had symptoms like nausea, bloated, hunger cravings ... now this month several weeks before my cycle is due I had some light pink blood and then I spotted the next day and then it stopped and now it's very light. And I am starting to vomit now from what seems like morning sickness.
