Could I be pregnant?

I am about1 week late for my period, i have never been late before.
I took 3 preg. tests, all came out negative. a friend told me that i should wait and test again in 7 days. Is there a possibility that I might have some kind of hormonal imbalance?

Ok so here it is..... I am now 33 days late. I was due for AF on 9/22, and she was a no show. I took multiple HPT's that all came back BFN :( and I also went and got a blood test done a week and a half ago that was BFN. So maybe I just skipped a period, or the blood test was somehow wrong? I am not totally sure. If I were to just skip my Sept AF, wouldn't Oct AF be here by now? And if AF is coming, I would think I would have the normal signs of it, but nothing.
I am normally very regular, AF would come every 3o days, without a doubt, but this time is very different. I would normally have sore breasts right before AF, and I usually get a bad headache the day AF arrives. I have been having frequent headaches, but no AF. I am so confused, could I possibly be pregnant, and the blood test was wrong, or is my body just completely out of control? I have also been cramping like AF is coming, but still MIA. Should I go to the Dr to see what the deal is(maybe pregnant, or AF is just going nuts) or should I wait it out to see if AF ever shows? I would love to be preggo, but I don't want to syke myself out if i'm not. Also, has anyone ever gotten a BFN blood test, but was still preggo? Any advice is greatly appreciated.Thx! :) Randi

We have been trying for our second baby for over 12 months now and using MyMonthlyCycles to chart my periods and ovulation dates etc. I was never regular until I had the Contraceptive Rod (implant) removed last year now I am every 30 days. For the first time in a year I am 3 days late. I did a pregnancy test this morning and it's negative!!!:( Yet I was sick last week and have heavy breasts. (Maybe wishful thinking?) Going to wait for a few days to do another-or do you think I am having a phamtom pregnancy! So fraustrated!

Hello,

I am 3 days late for my period. I took a test last night and it came up negative...so is it possible i am pregnant and its just not showing up on the pregnancy test? or am i just late for my period? =(
someone please help!

I chart my periods religiously..probably close to an obsession. I should have had a period as of last Wednesday. Today is day #6 and still nothing but each test comes back negative. I have an appointment today to see if we were successful. I hope so because I have been praying for a child. We have been trying for 17 months now and nothing. I know others have been trying longer but it's very frustrating. I hoping for the positive today. Wish us luck.

I'm a week late and have tested twice, but have gotten negatives both times. I'm having some symptoms, like lower abdomen pain (kind of like a stretching feeling), and I've been nauseated, but haven't thrown up. When I was younger it wasn't unusual for me to be late or even skip a period, but I've been normal for the past 6 or 7 years. I haven't been stressed out or taking any new medicine or any of the other reasons that would explain why I'm late. I'm thinking that either my body just freaked out and decided it doesn't want to bleed this month, or maybe since I bought the generic brand of tests, they weren't quite as good as the others and I need to get a different brand. Any opinions?
