i have never been very regular. but its around now that my period should be coming. my bf nd i hvnt had sex, but a few weeks back we did have an intimate night were his sperm came in contact with my clitoris, after tht i had a shower and everything, but now i feel silly for worrying that i could be pregnant, since the chances are very unlikely. on top of that i have had a lot of stress during this last weak due to a paper i had to write and i know that stress could also cause periods to be late. but a little re urance and/or mental peace wouldnt hurt.
