I don't know but suspect... help?

[Natalia]

I'm sorry if I'm out of place posting this here, but I thought with so many people here who have been mothers, or are expecting, that maybe I could get some help...

I'm 25 years old and have never been pregnant... I am a person who has very deranged menstrual cycles however, in that mine come tri-weekly, rather than monthly. I have a two week break, then a period, then a two week break, then a period, I've been like this since I was about 16...

Anyway, enough about that particular side of it.

I realised very recently that I've been through the entire month of April without having a period. I don't actually REMEMBER when my last period was, since I'm one of those lazy people who don't actually keep track of the date of my menstrual cycle, but it was at LEAST six weeks ago as far as I can tell. Nobody in the household can remember either (why would they know? Because I ***** chronically when I have my periods and scream with delight when they are over, I HATE them).

Anyway, for the past two weeks, I've been experiencing nausea that comes and goes (with only two actual bouts of throwing up, one was two weeks ago, the other was a couple of days ago). The nausea is accompanied by heavy and bad GAS, I am constantly belching, and often times when I belch, I feel as if I am going to throw up, but don't.

I'm constantly tired, last night I slept a full fourteen hours, and was woken up by my housemate this morning, and if they hadn't stood there and nagged me, I would very easily have gone BACK to sleep.

I feel bloated, in that I feel more fat and disgusting right now than I ever have in my life, EVER, despite not actually weighing anymore than I did two weeks ago, and I have slight back pain that has been bugging me on and off for a couple of days.

This evening I had some very light spotting, which I thought at first was a period, it was only very pale pink, and nothing actually came out onto a pad, but only when I wiped. This was gone within a few hours though, despite me having slight cramping to go with it.

Last week, my breasts felt weird. Not sore, like when I'm getting a period, but tingly and as though there were pins and needles in them. My nipples have also decided that they would like to spend much of their time poking out very erect to see whats going on around them, despite how hot or cold I am, it makes NO difference, they wanna stand up straight! In the past few days, my breasts have hurt slightly, as though I was going to get a period, because normally, for near on a week prior to my periods, but this has only been a few days, and it feels now as though the irritation has gone. I can touch them with no problems....

I HAVE done some of those home pregnancy tests, one brand called "Pregnosis" and another called "Imagine - One Step", the last test was last Monday morning, and the previous test was exactly a week before that in the middle of the day, because the test said it was okay to do it in the middle of the day (this was the same day I first had the mass bout of throwing up)...
Both have come up negative, but I am still experiencing all of the things I mentioned, and no sign of an actual period in sight...

I have a doctors appointment booked for next week and am going to try another home test tomorrow, but I am going nuts in the meantime. Everyone keeps saying to me "You could be pregnant" or "sounds like early pregnancy to me" and so many of my family members who have ever done home pregnancy tests say that they are so unreliable, they're not worth it. I do actually remember that when my sister first found out she was pregnant (from the doctor's blood test) she went home and did her left over home test (it came in a box of 2 tests) and it said she was negative, despite a doctor just telling her she was actually pregnant....

So, I don't know. Again, apologies if this is in the wrong place, or if things like this shouldn't even be on this website, but I need some help!
