Hi my name is Natasha and I have a big question about my mestrual cycle. It normally comes around the 15th of the month and ends 4 to 5 days later. This month I came on my period on the 17th and ended on the morning of the 19th. Since then I have been lightly spotting and this morning I woke up very nauscious. Could I be pregnant or what is the result of these symptoms?
