I haven't had a normal period in 4 years. It comes once in a blue moon and I sometimes have to take pills to get it. If I don't get my period naturally, I realize most of the time, I have little to no sex drive at all. Is this normal? Obviously if I am not getting a normal period, I am lacking in certain hormones to make myself sexually excited and aroused...like estrogen, prolactin, progesterone etc? I usually don't crave sex and therefore have no interest in forming a relationship with someone. This really upsets me. I also, is there anything I can do to get more of a desire?
