Hi Sunshine. You definitely are not the first worried pregnant woman to come here with questions and concerns...and you are most welcome here. I do hope that everything will go well with your little one.
I think that most of us exhibited signs of ectopic pregnancy well before the 9 week mark, as usually the tube will rupture when the baby gets too big. Every woman's symptoms are different, but in general, bleeding and pain are things that would be worrisome, as well as HCG levels that might not be doing the normal thing. (My ep started with spotting that increased to heavy bleeding...empty uterus on u/s...and eventually ruptured after a couple of weeks. I'm pretty sure it was all over by 8 weeks but it was 13 years ago so the details as to what week and all are fuzzy by now.)
Have you seen your doctor yet at all? You certainly can mention your concerns and maybe they'll do an u/s to confirm baby's position. Aches and pains are a normal part of pregnancy, and some women will also have a cyst from ovulation that causes discomfort. Your doctor should be able to help you know whether your symptoms are of concern.
Feel free to ask questions...we are here to help.
