I had bleeding for 1.5 weeks in my first pregnancy and everything was find, that baby is now 3.5yrs. I am 9weeks pregnant and have had light bleeding/spotting for 2.5 weeks of this pregnancy and lots of cramping (not severe but painful). Our 7week ultrasound shows a good heartbeat though. It's very hard not to stress about every pain and symptom in the first trimester. I still stress and this is my second pregnancy. Most of the ladies in here will say the same thing.
If you join the thread for the month you are due to have your baby you will find lots of support from parents to be in the same stage of pregnancy of you and your wife.
