David engineers Shaw pregnancies

I mentioned it as an afterthought in another discussion - but I'm convinced that I recognized an important detail in an easily distracted scene. Shaw begins experiencing severe cramps between Weyland's room and the 'Engineer's' lifepod. I realize that she just experienced surgery to remove the squid, and was subsequently stapled shut - but - the scene preceding the 'Engineer' encounter draws the audience's attention away from Shaw. Why then such emphasized, violent abdominal pains? My first reaction was - Shaw is still pregnant. But the surgery pod extracted the foreign body. For those who recall the queen xenomorph's reaction to Ripley's genetic imprint in 'Resurrection' - a new queen capable of two types of pregnancy resulted. She was able to lay eggs, and give birth similar to a human (mammal). Shaw obviously didn't react to the black viral fluid as Holloway did - but she is obviously a major catalyst in the xenomorph's evolution - and they do adapt to different hosts and their environments. The xenomorphs are foremost - survivors. Their viral origins may recognize an opportunity in an otherwise hostile environment with limited host availability. The xenomorphs do exhibit a hive mind capacity. So ... when the 'Engineer' was initially paying attention to Shaw's distress - could he have sensed the corruption ... but then...did David antagonize the 'Engineer' in a deliberately non-subtitled dialect. Shaw may be carrying a second xenomorph - possibly a new queen - maybe David knew from the initial scan, and provoked the 'Engineer' to 'Kill his Parent' as David suggested - and now David's intention's manifest. Shaw is impregnated - and alone. David convinced her to pilot another ship. What began as an experiment on Holloway has escalated into possible apocalyptic consequences.
