I have pretty irregular cycle. this summer i had a 47 days cycle... and then 38 days in september, 32 in october 31 in november, 36 in december and this month was the first time having sex. in january 30 days, and in february 28 days, and now my period hasn t arrived and it has been like 38 days. I ve taken a pregnancy test yesterday and it came back negative. but i have no pms ... I feel like i have the urge to pee the second i m finished peeing.... it s burning me when i pee a little and i have an itchy vagina. What do you think it is? I never pee after sex because i just can t ... i don t know what it might be, also do you think i m pregnant?
