Early Signs of Pregnancy?

Today for me was cycle day 31 ans my period was supossed to start. This has never happened to me before. I have never been late, no stress, no symptoms of my period coming or signs of pregnancy. I know that not all women have pregnacy symptoms til 2 weeks after missed period. Could I be pregnant? Im taking a cheap pregnacy test in the morning. Can someone, anyone give me an opinion or if it has happened to you and you turned out pregnant?

feeling a little sick, really bad headaches a couple of days ago, about to be 2 days late on AF. never been late in 23yrs, I go to bed around 10 everynight. but lately i can not keep my eyes open past 9pm....I been wanting sweets everynight the last couple weeks...I have to have something sweet. I don't know if i am pregnant or not. I don't want to take the test just yet..I'm tired of getting that one line.

I'm 14 days late today... I usually have a 36 day cycle and I'm at 51 right now with no period. I am pretty regular, but I've had a lot of cramping in the past few weeks and have been feeling bloated and full/heavy. There has been no morning sickness, I do have the occasional nausea when I even think about certain foods, but no breast tenderness or anything else out of the ordinary.
I know I should take a test ( I haven't yet...), but frankly I am scared. Over the past few years I have taken so many and they are always negative, I don't want to see that one line again.

So I am nine days late as of today. I have always been regular in the past. 28 to 29 days on the nose. I had a super short period last month and it was brown. My periods are always red. I am bloated, gassy, a bit nauseous, have some mild headaches in the evening and backaches. I took a hpt three days ago and it was negative. But, could I be pregnant??? I have no idea what is going on with me!

Hey ladies i'm a little curious. Now i was on bc for three months May, June, and July of this year. Got normal period in Aug 19, nothing in Sept, came on again Oct. 17, and Nov. 14, and now here is the 4th. I think is way too early for my period to be coming on since it is cd21, never got a period this early. Since coming off i was a little irreg but thought i was getting back to normal so what i'm asking is this my period or implantation bleeding or what??? So confused this has never happened since i've been tracking my period average out 30 to 32 days and i've been having symptoms like bloating, acid reflux and heartburn really bad (very unusual, tired, breast pain, nausea, raised temp, and backpain). Could this be pms or what, i usually get this way right before af.

So my Husband and I have been TTC for about 4 months now. Maybe 5? Not sure. Anyways, the first day of my last period was October 31 which was a day early. I have been diagnosed with endo but have not had surgery. So, based on my last period I am now 5 days late. I have been having these little twinges of pain in my lower right and left side and also having pains in the left and right lower sides of my back. The ones in my back actually kinda take my breath away. Weird? I think so. Should I test? I don't want to be disappointed AGAIN! Also, I have an 18 month old girl, with her I had sore breasts and no AF. No symptoms this time. Just tired.
