Tattoo cover up . im female and am i making a big mistake ?

im 27 years old and im booked in next week to have a cover up which will start from back of my shoulder and will run all way down my arm to the centre near your elbow ,,, so its going to look pretty HUGE . i have 3 horrible tattos im covering up which also have very bad memories for me, but im scared im making the wrong decision and dont want to look butch !! i cant afford to have them removed nor do i want to be left with bad scaring, the tattoo will be flowers and feminine tribal but only a tiny bit... what do you think please msg me back thanks
