I had a baby on nov 22 2014 , i had sex with my boyfriend new years night didn't use protection i was ovulating , then i started my period jan 4 does this mean it didn't take or should i still wait ?

Correct: One baby is 6 weeks old now. So, a couple should take a few months to plan for the long haul. Get married, settle down, plan the financial goals for the next 5 years,... which means wait until spring to start working on the next baby. The kids will end up about 2 years apart, and be buddies. If still worried about pregnancy, one can do a urine test in 3 weeks if no normal regular period comes.
