first pregnancy

i went to the hospital to confirm my pee test & they told me i definitely am pregnant but they couldn’t see the baby just yet on the ultrasound. because my period was just a month ago on sept 29th she said i could only be 2 weeks & my hcg level is 200 . but she wants me to come back to check the levels again too make sure im not having an ectopic pregnancy because im having period like cramps .. have anyone found out they were pregnant with hcg level at 200 & had period like cramps but still had a regular pregnancy?? im nervous & im scared because i don’t know how it works & i really want to make sure this pregnancy will be healthy & good... 😭😭😭
