Question about boa labor

Hi all. &nbsp;This is Raven. &nbsp;<img src="http://www.faunaclassifieds.com/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=''>

Here's my question/problem. &nbsp;My neighbor's boa is gravid. &nbsp;Last Saturday she began what my neighbor and I thought were contractions. &nbsp;We were able to see her moving the babies further down her body, closer to her vent. &nbsp;After several hours, you could see that the mass had moved to the lower half of her body. &nbsp;After that was accomplished, she just stopped. &nbsp;No birth, no signs of any distress, nothing. She doesn't act as if she is in any discomfort, no signs of distress even now, for all appearances she appears to be doing fine - still active, still moving around her cage, still drinking water, everything she always does. &nbsp;Is this simply part of the birthing process? &nbsp;Do they, like humans, have the young drop further in the womb days/weeks prior to birth or should she have given birth by now after this event? &nbsp;

As a side note, we weren't expecting her to give birth until later in the month but thought we may have miscalculated. &nbsp;With my own boa, once she began labor with her first litter, she gave birth within hours. &nbsp;It is possible that I missed this process the first time because my boa remained in her hide until she gave birth. &nbsp;My own boa is also expecting to deliver later this month or early June and I have seen none of this behavior with her this time either.

Any help or comments would be appreciated.

Thanks,
Raven
