Late Birth Control Pill & Missed Period: What Should You Do?

Question
hi, i took my birh control pill tri sprintec, four days late.  i've been spotting on and off for a week now.  i'm supposed to get my period today or tomorrow.  i took a pregnancy test two days ago and it came out negative.  i took another one this morning and it came out negative aswell.  still no period.  could i be getting by period four days late being that i took the pills four days late?am i more likely to be pregnant than not or the opposite.  please be honest, whatever it is, i won't hold it against you.  i'm married with two kids so if i'm pregnant i won't be devastated.  please let me know.

thank you!!  

Answer
If the pregnancy test is negative, you are not pregnant.  You are probably late because your body is confused because of skipping 4 days of pills.  Your body gets used to the drugs being in your system and when they are not there, it doesn't know what to do.
