I'm confused! My boyfriend & I had unprotected sex just 8 days ago (Jan 11th). I have not experienced implantation bleeding or morning sickness yet, but I have been very tired, going to the bathroom a lot, and the sides of my stomach are getting firm. I took a home pregnancy test today (Jan. 19th) and it came out negative..! Lately I have been getting my period on the first of the month so I'm concerned. Did I take the test too early?
