me and my husband are trying for a baby . we have charted and did our homework and have had sex on the days we were supposed to . and lately i have been feeling really sick and have been sleeping more than ever. i havent missed a period yet, but i have some signs of early pregnancy. i took a preg test and was negitive... but the problem with that is with all 3 of my kids the pregnancy tests were negitive until i was about 10 weeks. can u give me some more signs that i may be pregnant.
