7w symptoms

Caitee • Pregnant!!!
So I'm concerned and not looking for any rude comments please just helpful ones.. My Hcg levels have done nothing but go up, and I had an ultrasound and the us tech said everything looked good but I still haven't had much more than occasional constipation... No breast tenderness, nothing. I know some women are thinking must be nice... But before my daughter I had a miscarriage and I had no symptoms, with my daughter I had them all and a successful pregnancy and delivery, now here I am, pregnancy #3 with no symptoms and now as I hit week 7 I am having some period like cramping but no blood or sharp pains.. Could this be because constipation? And should I be worrying because I'm not having frequent urination or tender breasts? All opinions help. Please and thank you.
