So I am over weight and I know I need to lose weight and my boyfriend who is skinnier than a twig and I have been trying to conceive. I've taken one test ready and it came back negative. But I need help because my body weight I have NEVER had a regular cycle! This app doesn't really have that as an option because I haven't had one in YEARS in 21 5'9 347 pounds and haven't had a period in almost 4 years. When should I take a pregnancy test to see if I am pregnant? I keep trying to google it but it just says after first missed period and my Dr. Said my missing my periods is normal for someone my weight so it's hard for me to know if I am pregnant! Can ANYONE help?
