I had itching a few weeks ago on opening flaps of vagina. i was abroad and not having regular sex with my boyfriend. came back and we had sex. itching still coming and going, mostly when i swim or at night. recently been having dark brown discharge for the last couple of days. seems to have gone down. took home preg. test yesterday and today- all negative results. No odour down there. I have irregular periods- usually a month and a half to 2 months in between. my last period was just under 2 months ago. no other signs of pregnancy. please reply urgently!!
