possible that testoserone is more than my oestrogen?

hey! i'm 18yrs old and have not yet had my period nor have i had sex. i tried several times to have sex but my bf told me that there is some kinda bone that is blocking there. i tried to put my hand there but i did not feel the bone, well i did not feel within the vulva, just pressed around it. the bone to me, is circular and gives a passage for sex but idk. another thing is that a few years back i had a ultrasound done and the results showed that my uterus is smaller than normal. that was when i was 15. i have now started to freak out since i've not had my period and its about time. i feel so irregular. is it possible that the little testoserone that is found in the sex hormones is more than my oestrogen? i also experienced abdomenal pains around the item when i found out that i had the small uterus. i have all the other necessary thing; hair in the right places, breasts, my shoulder is broader than my waist but that is a trait that i may have gotten from my father. i'm freaking out!
