Hi, I Am A 23 Year Old Female. I Try

Hi, I am a 23 year old female. I try to work out about 4-5 days a week, eat clean (no fast food, no dairy, no soy and very little breads) I just started working again, I am always hungry, exhausted and my anxiety is through the roof. I don't know what is going on. My husband and I do have sex regularly but are not trying to get pregnant but I am not ruling that out as a possibility, but hesitant about taking any tests till I get more symptoms. Thanks for all your help!
