Could I be pregnant?

i am now 2 weeks late for AF as of tomorrow.i have had headaches for over 2 weeks (i never suffer headaches ever) im also getting mild cramping and back ache everyday for over a week now... i got BFN on the 9th and went to see a nurse on the 11th and to my surprise she told me i had tested to early i had a BFN on the 12th and iv been adviced to wait untill the 15th to test again.... what is going on im really confused? my cycles are normally 28-31 days.

So hears the deal i hav'nt had a period since the last weekend in febuary (24 or 26). On the 27th of march i had i tiny spot of pinkish red, so i thought it was coming, it never came. And no more spotting either. So that same week i staing getting a lower back ache didn't think anything of it and had that for week and half. March 30th started getting mild cramps, and have had cramps off and on since then, April 2 my boobs started aching My nipples are sore and boobs look fuller, also felling bloated in lower abdominal area, pants are hard to put on Nothing fits! And i feel like im constanly peeing, i used to work a 4-5 hr shift w/out using the bathroom, n now thats immpossiable it feels like pressure, have to go almost every hour. And i can only seem to wear soft sports bras. Sorry but i also checked my cervix for clues n it was soft and pretty sure closed. Its driving me nuts i've taken 6 test (but a couple dollar store tests also) only 1 EPT that 1st week in April, and 1 FIRST RESPONSE April 6 that were all NEGATIVE. I need some options im scheduled for a blood test next tue, but anyone else who had false negatives? P.S. my cyle is never late!

So now I am playing the waiting game. I went to the lab today and got a blood test done, because the doctors urine test was negative!!!
I just find it odd that I had 5 positive tests and the doctor was negative.
I'm hoping everything is ok, wish me luck!

Ok so I took 3 pregnancy tests in the past 2 days. You see, I worked l days without using the washroom, so i took the test when I got home. I automatically saw the "test worked" line and waited the 3 minutes. From the counter top it looked negative but when I picked it up I could sort of see a 2nd line! I waited a couple hours and took another, it came out negative completely.

I took another test the next morning using the morning urine, and it looked the same as the first test, I could hardly see the line. Now do I consider it pregnancy or are my eyes playing tricks on me? I'm wondering if there isn't...ahhhh

Has anyone had a positive PT with a line they could hardly see, i'm talking like it looks negative while still laying down!

I need HELLLLLLLLLLLLLLLLLLLP!!! I know every females body is completely different and the way one would experience signs and symptoms can be completely different than the next. Although I know this, I'm still trying to get an idea as to what MAY be going on with me. AF is pretty precise as to when she's coming to visit and I can count the day to be exact as to when she'll arrive. The exact pattern is the 26th day of my cycle I'll spot sometime during the day and then nothing else for the rest of the day. The next day (27th), she comes when her luggage ready to stay for a little while. It's been exact for the last 9 months. The last time AF visited was March 4th, in which I should have been expecting her visit March 30th. That day has come and gone, in which I am 2 days about to be 3 days late. As of now there are no signs of AF, only spotting. Because I've been pretty dead on with the timing of when she comes, I took a test after the first missed day...a BFN!!! Although I was trying to psyche myself into NOT getting too excited about it, that BFN got me down. I've gone to numerous sites and they all give signs and symptoms that I'm either experiencing a few here and there or nothing at all.
Can someone give me an idea as to what's going on? PLEASE HELP...

I am in the two week wait. I ovulated last week (6-8 days ago) and yesterday I had brownish pink spotting for the first time in my life. My period isn't due for another 9 days or so. Could this possibly be implantation bleeding??
