Could I be pregnant?

I was due to start my period on the 27th of sept (with a possible late start date of the 29th, if my math on my July period was off by a day or two) it's now the 1st of October and no period not even cramps, my breasts are swollen and ache, I'm nauseous on and off through the day and it seems to be scent triggered half the time, I feel like I have to pee all the time even when I don't actually need to but the test I took on the 28th came back negative. Should I just guess I tested too soon and retest in a week or two?

I feel pregnant but I'm scared to trust my instincts on this as I felt pregnant last month but had my period 3 days late (it was both very short, 2 days, and very light) my best friend swears that was implantation bleeding but wouldn't I have tested positive by now?
Ugh I'm confused..help!

Once again i'm in the tww. Im going so crazy. April 26, 2008 i had a misscarrage we waited as the doctor instructed to before tring again.We just started tring again in July and still nothing. My last af was Sept. 7 i cd 27 days. i ovulated on or around Sept. 19th. My next af aint due til Oct. 4th. My breast hurt, my nipples are darker then normal and i have dark vains showing on my breast. And i'm so tired. But i think that because we've been tring for going on two years now, That i'm letting myself believe that it's possible. I want a baby so bad at first we started tring because we wanted a little girl a little sister for the boys. but now i just want a baby a boy or girl will make me happy.

My husband and I have been trying for almost 2 years. I finally, at the begining of September called my Dr. We decided that fertility meds couldn't hurt, so he put me on Clomid. Shortly after, when my eggs were mature enough to drop, he dropped them all at once with a shot. This was on the 22nd of Sept. Ovulation was on the 23. On the 28th, I took a pregnancy test to humor a friend, and it came back positive. I have taken one everyday since, and it still comes back positive. When I called my Dr. office, I was I told to call back when I had missed my period, because I may not really be pregnant. Why would 3 tests come back positive if I am not pregnant?

Last month my period was light-med. and only 3 days. So I get excited, right?! Then september comes and almost goes and I'm thinking that I must be Prego!! My breasts have been sore like they were with my first child, I have heartburn, whitch I never had until I was pregnant with #1 and haven't had since; headaches too; and let me tell you! I am in the bathroom just about every hour!!! I can't even sleep through the night anymore because I have to use the bathroom! And on top of everything, I am extreemly bloated! Then yesterday "mother nature's monthly gift" arrived! Talk about upsetting! And I would think that I'm not expecting, but I have never had pms symptoms like that before and because last months "period" was only 3 days and light! What is going on with my body?! Can anyone relate? I really want to be pregnant again!! :)

well i have been getting sicky felings peeing more frequently swollen breasts and tender breasts and just that feeling, this months cycle is supposed to b longer because of my longer one last month 37 which is the longist its ever been it used to be 29 days and then my period.

well today i was due im a morning period person always have been. so i took a pregnancy test today it came up positve after the dye ran through about 1 min after but about 10 secs later it dissapeared and ive read these are negatives, but i didnt test positive with my daughter until 3 weeks late. has any one had one of these before. im gonna wait maybe a couple of days bfoe i test again...

I am 32. My husband and I have been trying to get pregnant for about 6 months. I was recently diagnosed with PCOS. I haven't had a period in forewver and not even sure I am ovulating but the last week or two I have been really extra tired, lower back pain and some nausea. I have not had any spotting. My breasts are sore. I have also been extremely sensitive to smells lately. I have taken a pregnancy test. It was negative. My ob put me on progssterone to induce a period and that has not happened. Could I be pregnant?
