My husband and I have been trying to get pregnant with our second child, and sadly I don't remember any signs I was pregnant with my son the first time. I had what seemed like a normal period flow just only for 2-3 days with him, and it's happened again but for only 2 days. I've noticed the tips of my nipples are becoming more sensitive, but no darkening of my areoles. I have been feeling drowsy but not a lot. I took a home pregnancy test with my son when this occurred before about the same time as now, and it came up negative, but I wanted a blood test done too and that came back positive...and I was 7wks and 4 days when I found out about him.....so I took a home test yesterday and it came back negative.....my periods are normally 6-7 days....when does the body give off enough hormones to give a positive reading on a home pregnancy test?
