<s>[INST] my name is vikki and i recently had a baby on october 28th 2010 i recently took a home pregnancy test on february 17th and it came back positive. I went through my calendar and seen that my last period was on the 24th of january which means i am not expecting my period till about the 24th or 25th of february. is there any chance that i could of got a false positive due to the circumstances or is it more than likely that i am pregnant again? [/INST] Hi, Thanks for the query I understand you concern.  There are two possibilities.  -Mostly It's rare to conceive after delivery... specially when you are breastfeeding.  At the same time spontaneous ovulation can occur. If you are not/irregularly feeding your baby -At the same time false +ve pregnancy test is also possible with Contaminated urine sample or contaminated contender in which urine was collected *Better way to repeat the test with careful collection of sample in sterile container... for confirmed result.  Thanks. </s>
