As per my blood reports, beta HCG is less than 0.1 mIu/ml. However, I am experiencing localised pain in the right lower pelvic region. I first had it on 2 April. It subsided after taking a pain killer, but used to reoccur. Since 27th night, I am experiencing continuous pain in the lower right pelvic region, with tingling sensation in my right leg and sensation that starts from the buttocks and travels down both the legs. I occasionally feel pain in the lower back and sometimes near the anus. Could this be due to ectopic pregnancy. I also have PCOD and I recently engaged in unprotected intercourse.
