Fumes were detected on two separate flights at the same phase of taxi/takeoff on the same aircraft. During taxi prior to take off; a strong putrid smell of rotten eggs or rotten dairy was permeating in the first class galley. It happened two times (that I am aware of) FA1 (Flight Attendant) and FA3 detected the foul odor. This happened at the same phase of taxi/flight on [flight out and flight back]. I do not remember the smell at any other time; as I do not have a good sense of smell. After finishing the safety checks; I did have a minor nosebleed on the [flight out] segment. I do know that I am not feeling well; and abnormally tired/achy; as I write this. Proper maintenance [required].
