Pregnancy Question!!

So, a couple weeks ago, I had some pregnancy symptoms. Now, considering I'm a woman and we all, at some points think we are pregnant
I tried to ignore. Eventually I had my period. So I thought okay, look at that, there is my answer! Well, now I'm having even more pregnancy symptoms! Extremely, I mean SO tired!! Boobs hurt, I have gained some weight. I feel nauseous in the morning but no throwing up except once. I should go to the doctor and I will! Just want to know the publics opinion first.
