Pregnant or not?

So I took a pregnancy test today, and it was a positive result. I heard that it’s better to take a 2nd one just in case. I’m having weird cramps every now and then, my muscles in my thighs,hips,butt, and pelvic area feel like they are pulling. Im not in too much pain I can just feel it a little bit. The cramps however somewhat hurt. However, one thing is really strange to me. Im really hungry most of the day, and I eat normally but sometimes I just don’t want to eat even though I’m hungry. Is that normal? I’m six days late on my period as well, and I feel like this test is correct, but I’m not 100% sure. Are these symptoms normal for a pregnant woman this early on?
