1 Incubation time varies with species, clutch size, and temperature and humidity in the nest. 2  The incubation time for most species is 45 to 70 days.  Research indicates that the sex of an embryo is determined sometime after fertilization, as the embryo develops, and may be temperature dependent.
brown discharge usually does not indicate a period. It could very possibly be implantation bleeding, however, as your using a condom every time it is unlikely. But still possible. If your actual period doesn't come I suggest a HPT. I'm not saying your pregnant, but it is possible.
discharge. 1  i am in pre menopause stage. 2  however this month i was expecting it to come in february, but instead i only got small portions of brown discharge. again i am not sexually active so i dont understand the cause of this. 3  I had a brown discharge 3 days after my period ended. It was light. All my periods have become lighter lately. I also have the signs of peri-menopause (I am nearly 48). I had a pap & HPV test about 8 months ago and they were fine (3 good in a row).
