I am 20 year old female. I haven't had my periods, I gave birth december 2018. I and my partner had unprotected sex several times and I palpated my abdomen and felt something hard which comes with pain as I palpate, I did home pregnancy test and it was negative. What could be wrong? I am hiv positive and my partner is negative, i've been on medication for almost a year and my latest results were undetectable, my partner and I had unprotected sex several times. What are the chances that my partner is infected?
