I had my last period on 15th of August 2017. I had sex with my boyfriend on somewhere around 23rd aug I guess, using protection. I was supposed to have my periods on the 15th of September but didn't (though I am quiet irregular every month). I did home pregnancy test on 20th and 21nd early morning and it came negative both the times. But still I missed my period the whole month of September. (Have missed one month once or twice when I was a virin tho). Today it's 6th of October and I still haven't had my period. No such pregnancy symptoms,just frequent urination. Expecting it on the 15th but very much worried and tensed. I wake up everyday thinking about it. Please help.
