I am on birth control but missed my pill and took it late a bunch of times. Around november 28-30 i had my period. Then in december i didnt have one, & had unprotected sex with my spouse the 25th of december, & the 4th of january, today is the 9th of january and im having a light pink blood on the toliet paper when i wiped lastnight and this morning, none throughout the day. After NOT having a period in December i took a pregnancy test around the first of january but it sais negative. I have more but waiting a few weeks to take them because im not sure if i took it too early or what? But its now january 9th and i havent had my period yet this month either.. Please give me an estimate guess or something, Please help!! Thanks!
