Bit of a strange one for ya. My period normally comes around the last week of every month. I have just started a new job and I was really sick with a cold/flu virus type thing aswell, so I figured maybe the stress/illness delayed my period. But it's been nearly 2 weeks now. So last night I had sex with my boyfriend and as we finished we realised there was period blood all over us!! I was relieved and glad my period was here. But since then nothing has happened. I kinda feel like I'm on my period but there is no flow! Nothing coming out! It's like I'm 'bunged up' with period. Should I be worried? Can this happen? Am I going to have to have sex everyday to get my period out!? haha!
