Hi. I am usually 27/28 days with my cycle. The first day of my last period was Feb 17. My projected start date was March 17. It is now March 23 and I have had spotting from March 20-22. Today I saw no spotting. The spotting was a brownish color. My boyfriend and I have had sex 4 times between the end of my last period and March 7. Every time we used a condom. I am worried sick that I am late and I was happy that I saw spotting but now it has ended. I have taken multiple pregnancy tests and they have all shown negative thus far. I read some women didnt get a positive reault until 7 weeks after their missed period. I am really not ready for a baby and now I am worried the condom somehow failed? Please help!
