Every time I was pg, I knew right away. With 2 of my pg's I had symptoms and with 1 i didn't, so save your $ and wait it out.
I knew too! I got it confirmed yesterday, the day before my af was due!!
I'm just knew. i can't explain it, i just knew. I never had a pd. in between my two girls. my oldest was just a month old. I had a feeling i was.I went out and got a test and sure enough i was! The doc. confirmed it at my 6wk. check up. I just had a feeling.
With all of my pg's I found out before I missed af, but that really doesn't mean the same will hold true for you. Save your money, wait and see if af is late before testing. I swear if I had a dollar (or even a nickel) for every woman on MH that tested too early only to have af show up a few days later, I would be a rich woman.
My advice again, is to wait until you miss your period. No sense in wasting money.
