Extreme fatigue early pregnancy should I sée a doctor?

I am so scared and my mind has been all over the place. The past several days, I have had lots of symptoms that point to early pregnancy. Nausea, extreme fatigue, and a high emotional state. I'm due for a period this weekend, but obviously praying for the opposite. What makes it worse is everyone around me is popping up pregnant and it hurts because I've loss twice this year. Trying to stay positive and keep my Hope's up. If I don't start this weekend I will be testing next week
