back pain during early pregnancy

ovary pain in early pregnancy.?
Hi all, I have 5 weeks pregnant and last week I've been having pain in both my papers ovaries. Gererally is pain on the left side, but it does sometimes alternating and I feel it in the right side. I went in for an ultrasound (to early to see anything) and now I have to get my blood taken every 2 days. My uterus is tilted backwards I've read can cause more pain during pregnancy. I'm really scared, this is my first pregnancy. Do any of you (about 5 weeks) pain experienced this type in early pregnancy or currently experienceing? PS: I have no cramps, no bleeding, not faint or weak. Just tired all the time! Thanks for your help and best wishes to all!
I am 7 weeks and get a dull ache throughout the day on and off. I talked to the doctor who said my uterus was stretching. While hormone levels are rising every time you have made your blood then this is a sign too good. Try not to worry, but if it gets worse see a doc. xx
