Hello ladies! *If* I conceived this month then I'd only be about 2 weeks along. I know it's super early but did any of you girls experience cramping before you found out you were pregnant? Sore breasts (specifically nipples)? Fatigue?

I only ask because I rarely get cramps before AF. During, yes, like the worst pain, but I've been feeling slight twinges in my lower abdomen.
