So I had brown spotting for five days from Saturday the 25th thru the 29th, I know it wasn't my period because my periods are horrendous! I ovulated around the 17th and bd'ed on the 16th and 18th, so I thought it was implantation bleeding but my period was suppose to start on the 31st and im now 2 days late... Question is, if it tree implantation how long would it take to show up on a test? I took a frer curved test the day my period was suppose to start and it was negative. Anybody else have the same thing and wound up being pregnant??? Helppp.. Thanks!
