I was on BC pils for 3 months and I have sex when I was on the inactive pills on Jan 11th and 13 not using any protection. I had stop taking my BC pills on the 4 last days of the pack. When I'm on the BC pills my cycles are 36 days. My last period start on Jan 7th 2013. On jan 31st I had bright pink n brown spotting for 2days. My period was due to start 4 days after the spitting occurred on Feb 3rd. I took a pregnancy test on Feb 6th and it came back negative. Today Feb 16th marks day 40 since my last period and I was wondering if there's a chance that I'm pregnant ? And if I took my pregnancy test to early ?
