Early Signs of Pregnancy?

my last period was in march 04, 2010 i get my period every 28 days its already april 09, 2010 and i havent gotten my period i took a pregnancy test today and it came out negative my calendar says im 8 days late, ive been feeling really bloated thats unusual so i dont know what to do. should i go to my gyno? or wait and take another pregnancy test?

I'm slightly confused about my cycle and what my body is upto this month.
I ovulated around 20th march and had sex quite regularly around this time. AF was due on saturday 3rd april and took a HPT on sunday, I saw a very faint positive line which my patner couldnt see at all. I tested again on tuesday morning and positive line was there at all. I've been getting the usual cramps i get around the time AF is due, but no other sign of AF at all. Should I test again or just believe the second test result? both tests were done using the first sample of the day and were the same brand from the same box.

I normally get my period every 25 days. In Dec, Jan , and Feb it came in 27 days. In march it came in 24 days. Now in April this is already late in the 28th day heading into the 29th tomorrow. I have had tender breasts and it "feels" like my period is about to come, which it has been feeling this way for about 3 days. I want to have a baby, but don't want to get my hopes up and spend my money on a pregnancy test right away. Please advise.

Ive been having alot of different things going on since my period ended a week ago! and today as I was working I thought just for a second that my period was coming on again. It felt as if I was leaking or something, I went to check and there was creamy white mucus there. My back is killing me,my breast ache all day and the frequent urination is coming between my work and my sleep time. Could this be a early sign of pregnancy?

Sorry if any of this is TMI but anyones help/opinions would be appreciated!
My last AF was 24th March but I had sex on the 24th and 26th and my AF just suddenly ended. (usually last upto 4 days).
A week after AF suddenly disappeared again, I've just had a feeling that I'm pregnant, even though we didn't have sex during OV days..so I'm confused.
My average cycle is usually 25-28 days and never usually late. AF is supposed to arrive tomorrow but am having no signs of arrival yet, when usually I'd know round about now that she was on her way!

For the last few days I've been so tired, soon as I wake up and all through the day I just want to sleep. No tender breasts but lots of mid back ache and bloating. Some smells have upset my stomach and I've been getting headaches and nausea throughout the day which are normally rare for me and I feel hotter than usual, all the time. So much so that I've not bothered wearing a jacket all week when the weather is awful.

I realise I might just be worrying too much or imagining I'm pregnant, resulting in me experiencing all these symptoms but I'd really appreciate your opinions. Thank you! :/

I'm only 3 days late so I don't even know if i should have any symptoms according to pregancy calculator I would be about 4 wks 5 days pregnant..and for the record I took a hpt on the day of my missed period and it was negative...But anyways on to the symptoms, I am always tired but been feeling completely exhausted here lately.. I can sleep 13hrs and still be so tired..had some back pain but that may be due to somehow pullin my back out and just as my back was feelin better I woke up with a stiff neck..I've been feeling nauseous on and off and the same with cramps.. Today I ate a cheesburger and then felt kinda sick afterwards,this may be a lil TMI but I've also had some clear watery oderless discharge like sometime I feel like I started my period ..also off and on I feel like a tightness or even at sometimes a full feeling in my belly..my breast were really sore yesterday and then it kinda faded today until this evening an then they started hurtin again..also I don't know if this is something but I physically feel hit sometimes , I think that's about it... so what do u think Lol, I'll be testing again in 4 days:) wish me luck and baby dust plz
