I have never witnessed the same type of ovulation swelling that goes on with SA boas as with my Dumerils. By that, I mean that the swelling was spread out more on the Dumerils. Much like the pre-ovulation swelling that is seen in the SA boas. I checked my records with her and they were breeding from Nov-Jan. At that time the male had lost all interest in breeding. She did NOT POS, but did have an intermediate shed 2 months into pregnancy. I had assumed she reabsorbed as she has in the past. If I counted days from when I did see a slight swelling, gestation is around 5 months. IME female Dumerils always shed 7-10 days prior to birth of offspring.
I have another female that I consider a more reliable breeder and she is gravid as well. Her ovulation swelling was much more pronounced than the female that just gave birth so I knew she was a lock. Again, no POS. But she went into the HCP following her ovulation towards the middle/end of Jan. She has been opaque starting early last week and should shed shortly. Should have babies around June 10th. I know the accepted gestation for Dumerils is 6 months, but of the 4 Dumerils pregnancys I've carried out over the last 5 years- the length was less than 5 months from the time of ovulation.
