I Had Unprotected Sex Two Times in Less Than 24 Hours which was the 7 of march. Later the weeks I started having symptoms from headaches, quick sharp pains in my lower sides & feeling nausea but no throwing up. The 31st hits and I am 3 days late bulater on i started bleeding & thought it was my.period but it only lasted for 1day . I did my research and I know it has to do with implantation . Currently I have beem bloatef for the last couple.of days and been having sharp pains again. I took a pregnancy test twice just to check & both were negative. I'm confused and scared. Please help me! !!
