No period this month

Rachael

So I usually always get my period at the end of the month into the beginning of the next, well I still haven't gotten my period this month and last month it was like only two days w light spotting, when I took a test last month its was negative, I haven't taken a test this month yet but I'm really starting to think about it and if I don't get it and I get another negative should I make a doc appt!! Feed back ladies!!
