I tested yesterday, 4 days before my missed period, and it was faint but positive. This would be our second child and I'm extremely excited! I'm also overly paranoid that it could be a chemical pregnancy so i bought more tests today. I bought a 3 pack, Equate brand, and took one a few minutes ago..negative. I know I haven't even missed my period yet and I didn't wait to take it in the morning, but the cramping and gas has me so worked up. Again, I know that is normal but I just need a little reassurance!
