Could I be pregnant?

My periods are usually very consistent, and always come within a day or so of when it is due. I am not due to have my period until the 7th, however ive been having what I would call very light spotting since last week. Could this be a sign of pregnancy? Should I wait until after my period is missed to take a test? This has never happened to me before, so I am a bit confused, and anxious.

AF was supposed to be here on the 25th and its the 29th. I am going to take a test in the morning if she is not here by tonight when I go shopping. I have been trying not to think about it but I can't help it. We have been ttc for 4 years now, after a very painful MC. My Husband's birthday just passed and he made a joke about me calling him at work and telling him I was PG for his birthday present. I am afraid every time I use the bathroom that I will see signs of AF, please prey for us!!!

I have had a weird period for the last 3 months. in feb and march is very heavy which is normally not how it works with me. i started march 27th and then april 18th i started again. my breasts were very tender all month last month (in march and april). could i be pregnant or is something going on with my period.

My period is almost 3wks late and I've been having a lot of back aches. Could I be pregnant or is to my period?

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!
