Help Me! I am going crazy! lol

So I'm sure that you guys have seen me on this forum asking so many questions. So i have another one. =) My gf and i did a home insemination March 22 and 24. I thought all was lost when I started having some bleeding for 2 days (April 5-7) and then a little bit of brownish bleeding on April 8. I cried to my mother in law. She then informed me that it is normal to have a little bit of bleeding around when your period is due. (AF was due April 8). I keep taking hpt and of course they are negative. I am just wondering if anyone else has had these issues? I also have horrible breast pain and my nips are always hard or in pain. I just dont get it lol  Please. Lol I am losing my mind.
