hi, i have regular monthly period. On april 14 i went to pap smear and was worried when the OB advised me to undergo ultrasound. On April 21 is my expectation of my menatruaton and only few drops of pink fresh blood, but still i took my contraceptive pill then for i am expectating my husband will have to arrive by that month. 
On May 01 I undergone Ultrasound and found out some myomas, but what made me bothering is that although i am using contraceptive pill i have my pink fresh blood just few drops on May 12, and i am pretty sure i am not preggy coz he'l be arriving by next two months from now.
Any idea what's going on?
