A second pregnancy is not high risk. You can wait until you miss a second period. Prenatal vitamins are always a good bet
Did you read the test at the right time That means not letting it sit for a long time. When they sit, they do develop a second line and it is not a positive, it's an evaporation line. Beyond that, if you are getting positive tests and two at that, ya, you sound pregnant!!!! :>))))) We have a pregnancy forum. I found out I was pregnant and had the same questioning if it was real or not. But those tests when used correctly are very accurate. Congratulations!
