Hi, since January I went of the pill to try for baby no 2.  For the last 5 months my cycle is normal about 27-29 Days.  But the last cycle I missed my period.  I started testing from 7 Days late and show negative.  I'm now 20 days late on Day 49 of my cycle and started Spotting yesterday. Yesterday only one's and today one's again.  My breasts are also tender.  I haven't done another pregnancy test in over 8 days now.  Could it be implantation bleeding or my period starting.  My period is fairly regular, but not this time.
