I am stressing 😲😲😲

Okay so my bf and I had been trying for a year and had no luck but on December 13 was the first day of my last period and after we started baby making and on January 1st my breast started getting really sore and round and I was expecting my period since this always happens One week before my period instead 2 weeks passed with the same symptom. On the 3rd week I started getting Very nauseous over food i really liked. My sense of smell became very strong and was nauseous throughout the day vomiting only in the mornings. Last week I schedule an appointment with my doctor and she did a pregnancy test and came back positive. She only gave me a paper of things I should look after throughout my pregnancy and told me to look for a Maternity Clinic to get prenatal care and she couldnt refer me because they dont do referrals there. So that same day I schedule and appointment at another clinic and they said they had to do the pregnancy test again since my doctor didnt give me a paper. So i went monday and they asked me all this health questions like usual and then the doctor came in to do a pelvic exam and said i was fine. And send me to the lab to get blood drawn and also pee on a cup. Well they did that and they still didnt check my pee or if my baby was fine or anything they just scheduled a ultrasound for this Friday and told me to get Prenatal vitamins. Well I been soo nauseous still but I still force myself to eat. I was feeling my lower tummy and it felt squishy not hard like my first pregnancy. I weighted 123lb last week and since i had been throwing up I weighted 120lb this Monday. I am not fat but I am a little chubby.. I am freaking out because I still cannot believe my test came back positive. And i need to see the baby to KNOW forshure that I am pregnant. Has anyone else tummy felt squishy at about 8 weeks? I need reassurance
