Hormones stronger in the afternoon

I don't know why, but every day around five o clock it's like my symptoms come alive. I go all day and barely feel anything and then they suddenly appear. I thought it was supposed to be bad in the mornings ?. Even my pregnancy tests are darker in the afternoon. My feet get so cold for some reason and my boobs start hurting again. Not complaining thought because I'm thankful for every symptom at this point. I'm so happy to be pregnant, I just find it strange lol.
