Financial talk

okay so i had a baby exactly a year ago, and i have had very normal periods since. it would always start between the 12th - the 14th. which is the same as before i had my son since i was 13. untill just recently. on my birthday march 29th, was the last time i had sex with my husband before i was late on my period. i should have started this month in april and i havent yet. the date is now the 23rd. that means i am 11 days late or so. almost 2 weeks. the first time i was pregnant, i knew right away the very next day i woke up. and after 2 weeks...i took a test i was indeed pregnant! now im not so sure. i dont feel the same as i did with my first. and i dont know if this is normal after your first kid because its been almost exactly a year since his birth he was born on april 19th 2007. i dont want to spend money on a test if this is normal. so any moms out there with experiance could answer my question please would you? thanks jacqueline
