Me and my partner have been trying for a while now so that our little girl will have a sibling to grow up with, and i'm now 4 days late, and have been feeling queasy and have an ache in my lower back, the exact things i felt wen i was pregnant with my daughter and yet the pregnancy test says negative, im convinced i am but could i just be imagining it? my period has been every 21 days for the last 8 months, same time every 21 days without fail, i'm not stressed out or anything like that, works good, unis good, my family life is great...i couldnt wish for more, should i wait a few more days or wat?? confused!!!!
