Hey, I have a few questions. On Dec 31, I had unprotected sex a day after my period and my partner pulled out (the most he did was precum). I took the full dose of plan b on Jan 1st. I started what I think may be spotting on January 5th, it is dark red/brown and is not very heavy bleeding. I've heard this is normal and is caused by plan b. Is it supposed to be dark brownish? What are my chances of being pregnant? Also, does this count as my period or should I still get my normal period at the end of this month (or close to on time)?
