Hello, I married recently five months before, my hubby had unprotected sex once at past three month before but he hadn't ejaculated inside. As I missed my periods from the two months. But as my periods comes on 15 day of the month I. E. 15 august and I took my home pregnancy test at 19/august and it showed negative pregnancy. I ignored the miss of mensuration but now in the month of September period get miss again. As I have taken home pregnancy test twice it is showing invalid result twice. As there is lots of pain occur in lower abdomen I get stabbing feeling during the urination. Some times there is unbearable pain occur and nowadays I am feeling like cramps same occur in periods but periods doesn't occur. Kindly guide am I pregnant or I am suffering from UTI infection. And because of this my periods are getting miss from last two months.
