I have a serious question guys!

So today I'm supposed to be 7 weeks pregnant. I couldn't be happier after a missed miscarriage in August last year, was supposed to be 11 weeks only measured 9. My concern is that last time I was pregnant at 6 weeks I had nausea so bad I was in the hospital once a week for the last 3 weeks my baby was really with me. And now I haven't been to the doctor just went to the clinic to get proof of pregnancy and I'm starting to get really nervous as the point at which I lost my baby last time is approaching. I haven't had any morning sickness at all yet, should I go to the hospital and check up on my baby? I need real advice ladies
