Almost 6 months ago our son was stillborn at 28 weeks gestation. No explanation found after multiple testing on my son and myself. My husband and I have been trying to conceive again (doctors told us to wait 3 cycles). This will be our 3rd month trying. I've been tracking my cycle and using ovulation kits. My cycle length is very irregular. My period this month is late although I have a very tiny amount of brown spots wrapped in discharge and miild cramping. Is this a sign of pregnancy? Or should I be concerned? Is infertility common after stillbirths?
