early symptoms

Kristina
My cycle is only about three weeks so I ovulated around cd 12 using opks and the fact that I can actually feel when I ovulate. I'm 6 dpo and I have been feeling sick and nauseous all week. Yesterday I started to get intense hip pain that I had late in pregnancy with my dd. It kept waking me up last night along with the nausea. I just got sick after breakfast. With my dd I knew I was pregnant just over 3 weeks (8 dpo) because I was so sick and it lasted until week 14. It is way to early to test but could these really be early symptoms?
