Totally different symptoms and frame of mind

I miscarried in Sept with an unplanned (but wanted) pregnancy. Yesterday I found out I am pregnant again. I feel so lucky. Although I am obviously quite nervous, I do feel more prepared for this time round. Taking all the necessary vitamins and living a healthier lifestyle. Weird thing is all my symptoms are totally different. The cramping is pretty strong as well as feeling like I could crawl in bed any time of the day. Has anyone else had an experience like mine?
