first sign of pregnancy

so ladies I need to know what you experienced. my wife thinks she is pregnant. we are trying. right now is her obvulation time. she says she is cramping like a period, she pee'd about 50 Times yesterday, she's craving chocolate right now, her nipples and breast or sensitive the kicker is last night in the shower she squeezed her nipple and areola and a white substance came out. as far as the time line goes from our last love making session it's been (she says) 10 days. what do y'all think and what were your very first symptoms.
