Websleuths Crime Sleuthing Community - View Single Post - Raven Says . . . (some good links in this old post)
From what we know:
1) Janet's uterus was noted as "unremarkable".
2) The endometrium was thickened.
3) Raven mentioned her being in her normal "bad cramps" position.
According to the information I've found, by week 4 of pregnancy, you are just missing your menstrual period. By week 6 of pregnancy, a doctor can notice a change in the size of the uterus. If Janet's endometrium was thickened, then she was very near, at, or past her due date for her period for that month. So my guess is that she was at least four weeks pregnant but not yet six since her uterus was not noted as being enlarged.
What I find interesting is this:

Week 4
You're probably expecting your period this week, and if it doesn't occur it might be one of the first signs that you're pregnant. (My note: Many sexually active women take a home pregnancy test the day after missing their period.)

Week 5
Still no big changes to notice in yourself, although
you might suspect by now that you're pregnant.
Raven's claim that she was in her normal position for when she experienced bad cramps sounds to me like Raven at least knew that it was time for Janet to be having her period. Can we assume that he knew that she was pregnant? Not at all. BUT - he mentioned "bad cramps" as if he knew that she was due for her period, the lining of her uterus was indeed thickened, she was probably at the stage of pregnancy when most women usually take a home pregnancy test, and she mysteriously ended up dead. How odd that Raven mentioned cramps and that he found Janet on her knees - what are the chances that a murderer went into that home, killed Janet, and she somehow just happened to end up on her knees in the exact same position that she normally took for menstrual cramps so close to the very time that she actually
should have been having her period - leading Raven to believe that she was alive & suffering cramps when she was actually dead & pregnant? If he had "found" her on her knees like that two weeks earlier or two weeks later, surely he would have found it odd since she wasn't due for her period at those times. (And keep in mind that the position in which Raven claims to have found Janet was: 1) only seen by him, and 2) a very unusual position for a deceased person.) It all just seems a little too convenient to me - mentioning cramps when she was pregnant; mentioning shooting when she was stabbed, mentioning that she was "upstairs hurt" when she was dead, etc.
IMO, Raven said these things to separate himself from knowledge of the crime. And his mention of cramps leads me to believe that he was trying to separate himself from the motive.
