More to the point i'm wondering i anyone got a true positive. I'm -4 days before my period and feel horrible. sick and period type pain. I got this with my last pregnancy. Going out of my mind... And i'd really like to test, but can they work or would i be wasting my money? This is our first month of trying, but i'm among the truely very lucky type that fall really easily. I am also really in tune with my body, but doubting myself cos i'm... well, i don't know why really but ykwim.
