Google "lightning crotch"...hope this helps!!! :-)
Might be a kidney stone. I heard they are more common in pregnancy but ive had them even before becoming pregnant and i too also get that pain your describing. Im not a doctor so dont take my word for it but it might be a possibility. Goodluck
Yes I agree with mamaofdeux my dr told me I can take Tylenol Extra Strength iT is to uncomfortable:)
It sounds normal to me. Combination of your pelvis shifting and baby kicking a sensitive spot. I usually get if when I walk around too fast or don't rest enough. Just one of those downsides of pregnancy.
