hi,

i had my period on 15th of feb. i usually have a 33-34 day cycle. i had some bleeding on 15th march night onwards until 17th mid day and some minute spottings on 18th. my period was not due until 20th or 21st of march. So was it implantation bleeding, can u say if i am pregnant ??? i am having sever lower back pain since then, i have never had a history of any back pain. the only time i had was for my first pregnancy which was a miscarriage in eight weeks otherwise never any back pain .
today is the 3rd of april and i did a preg test which came negative. should i wait more longer to do another test ??? can u tell if i am pregnant ???
