ultrasounds..

i posted this like a lot of times already but i have a transvaginal ultrasound that i 'should' do but i dont know. im super super nervous, still a virgin and idk. i think after i get my blood work done she'll (probably??) call me into the office and im going to tell my doctor id prefer not to do it at the moment.. im just afraid she'll not prescribe me my birth control since i dont want to do the ultrasound.. i love my birth control it makes me feel a million times better. what do you think?? i just dont think its right for me right now... thanks for listening.
