We have been planing for a baby and recently my wife has missed her period. Her periods are rather irregular and ranges from 35 to 40 days. Its 41 days today and till date there is no sign of period. Although she did have some cramping and lower back pain. She also had some spotting of brownish color which lasted for three days during the middle of her cycle. We have tried the home
pregnancy test 4 times and always it has shown negative. Pls advice
