Should I see my MD? Late AF

Holly
I am currently 2-3 days late for AF. I have taken a pregnancy test (from the dollar store)  this AM and it was negative. I have had lots of sx over the past week and a half. Extreme bloating, dizziness, nausea, sore breasts/nipples, fatigue, headaches, runny nose and stomach pain/cramos( not like menstrual pain). My husband and I have been TTC. 
Thank you!!
