My last period was on August 28. I had unprotected sex on September 24, but he did not ejaculate. It is now October 6 and I have not gotten my period. I wouldn't be a bad thing if I'm pregnant, but it would be unexpected. I have been really tired this whole week and I have also been getting a lot of minor headaches along with white milky discharge. I am wondering how soon I can take a pregnancy test?
