late period, should i worry?

I am currently taking birth control pills, i have gone through the first three weeks of active pills and am almost done with the last week of active pills, i will be done with this last week of them in one day. I still haven't gotten my period yet, so i am quite worried. Before i started taking the pills it was usually almost a week late, but now i'm worried :-/ should i just wait and see if i get it soon? should i be worried? or is the pill just messing around with my cycle more?
also, last week i was taking antibiotics for a urinary tract infection, could the antibiotics have delayed my period? argh, i'm worried because i start the next pill pack tomorrow and i still haven't had my period :-/

 

My GF actually missed her period last month. We took two pregnency tests and she went and had her blood tested. Everything was negative. The doctor attributed her missing period to stress. I believe it, she has emotional problems. In your case, I wouldn't be surprised if the antibiotics had something to do with it. They tend to throw your body out of balance. I would see a doctor if it doesn't occur soon; save yourself some stress. Then again, I'm a guy so...

 

i didn't read your post but however my periods are late ALL the time. I cannot go on birth control because it conflicts with my medications. I have tried to go on birth control before and man i have never bought so many pads in my life. I am usually 2-7 weeks late for my period always!! LOL!! One time i was 2 months or 3 months late and my husband who cannot have kids anymore said to me "you might be pregnant"
I said how?? Your lil dead spermy ?? lol it just turned out it was stress between school work placement kids dance and coming home late and homework!! College is a lot of work and than again so are kids when they are teenagers !!! I just want to mention to.. When i was on BS i mean BC HAHA i didn't always get my period on time either quite weird i'm afraid to go on it again for weight gain problems and what not!! i gained 15 pounds last time which sux
