With all my pregnancies around 2-3 DPO i had cramping, with DD i felt 'heavy' down low, i compared it to feeling like a baseball was in my uterus that how 'heavy' it felt. Then at 6-7 DPO i had more cramping. Which i always knew i was pregnant as i would have consistent cramping leading up to AF.

With DD i was horribley tired right away, nausea set in from word go and the day i tested (10 DPO) i had a big dizzy spell at work. I tested that night and got a very faint BFP

I actually got the flu when i first found out i was pregnant the second time around so can't say what early pregnancy symptoms i had

With DS i felt nothing, i felt fine just AF hadn't arrived then when i hit 7 weeks is when i started feeling sick/vomitting and very tired.

HTH and good luck!
