Not2Sure

Okay first time doing this, so bare with me. But i seriously need help. Well last time i actually had sex was in Dec. Well Dec 12th. I had so many sisters and realtives in and out the house, and so my period didn`t come till january, and i know how if you are around other woman for a little while or etc, that your period comes later or earlier . . if that is true. and my sisters don`t live here and neither do my realtives they were just here for christmas vacation about a month. well anyways, period didn`t come till january, and even then it was late, and it was only for 2 days, and it wasnt heavy at all. but it was bleeding like a period. i have taken a couple of pregencey tests and all are the same, febuaray came and since it was a short month, i thought that was the reason i didn`t get it than. then of course now its the end of march, and for like a week, going on 2 . . the only time i see blood is when, i wipe, and then its really light, like you can barely tell, and i don`t know if it`s blood from rectum, when i do a bowel movement, but i know when i go to the restroom (number 1) i wipe, and then its light blood. but this has been going on for like i said 2 weeks now . . so i don`t know what it could be. i mean no cramps or nothing, for the past 3 months . i try to mess around with my breast and belly to see if any pain and nothing, i have no vagainal pain or rectum pain either. i don`t know what it is, but then again going to the doctor and him telling me that something might truly be wrong with me, like cancer or something would just shatter me, i know it`s better to know but, my GOD. and probably just like a week ago i also had intercourse. but still nothing, no blood or nothing, once again except when i wiped. the last 2 months i have had a stressful job that i just now quit recently about 3 weeks ago. umm i also ya know, had a big change in diet, not drinking or eating much of anything. really staying away from liquids and foods, cause of so much on my mind. but now i`m fine and with a good job and ya know happy, but this is really worrying me. so please someone help if ya can. it probably sounds crazy but i tried to explain it the best i could. thank you
