I took a test today and it said negative. I can't even SLIGHTLY remember when I had my last period and I'm not sure if it's too early or too late.

My symptoms:

Tender breasts (Kinda on the sides of them)
My stomach is hard, but it sticks out higher up than it usually does.
Tired/Fatigue
Throwing up in the mornings and evenings.
I've had terrible mood swings, and I don't even notice until I'm done 'swinging', I guess.
Very weak.
Constipated (The last couple days, but I finally solved that problem.)
Sore muscles.

Is there any other 'old fashioned' way of finding out if I'm pregnant or not?

If you can't remember when you had your last period, there is something wrong, even if you aren't pregnant. You need to get to a doctor, have him confirm you are or you aren't pregnant, and if you aren't, you need to find out why you haven't had a period in so long.

I know I had it last month, but I can't remember if it was in the beginning or in the end of that month, I've been so moody lately I can't even think.

Ohh okay, you made it sound like you hadn't had one in so long you don't even remember :p

It is nearing the end of this month, so I would say if you don't get your period by October try testing again. Since you don't remember when your period was, it may very well be too early to detect.

That is a very good idea, but my nerves are killing me about whether I am. Ahhhhh

I know the feeling, but you have to try and relax. Your nerves and you stressing out can delay your period, or even make you skip one. Just remain as relaxed as possible and if you don't get it by October, try another test. Make sure when you test you use your first morning urine when you wake up in the morning. :)

Sounds like a plan. Thanks for the support!!

You're welcome and if you have any more questions now or in the future feel free to ask :)

Thanks so much!
