Listen to the doctor or take an test?🤔

So I have Question ladies so I start my period next week and I am on BC by the way. But I have been feeling so damn off for about 3 days now lol I am tired, shaky and have chills. It feels like my period is about to start I know it but I recently took 2 pregnancy test the other day those came back negative and I went to the doctor yesterday and she did one on me too that also too came back negative. The reason I took one was because my breast where hurting just alittle and I was just feeling tired so I took one because I am paranoid person. I don't feel sick or anything like that but I have no energy. I have been really stressed lately and I feel like everything is on me so I haven't gotten no me time to myself. So the doctor thinks it's because my period is coming and I am stressed so I should get some rest. So I not worry and listen to the doctor or take another test?
