Last month I got periods twice.One starting from 1st March to 6th and second one started from 15 to 21st. I got intimated with my partner on 27th of March but there is no coitus happened. Now ,this month I am 8 days late for my period and for the confirmation sake I have checked the
beta Hcg that is also negative. What could be the probable reason?
Is it related to UTI infection because I am suffering back pain , abdomen pain and knee joint pain.
