20 dpo but no test has been positive what should I do?

Kayla • My husband and I agreed on that we don`t need another kid for 5 more years.
My last period was August 23 2014 and I spotted on 9/9 and 9/10 but not enough to use a pad or tampon. All my tests I take are neg but still no period. Been getting cramps for the last week but no AF and slight tender boobs. Ugh HELP
