В ожидании первенца

1st pregnancy & would love feedback from seasoned mommies!

So I am 29 years old. Me and my husband just found out that we are pregnant. This will be our first baby. I am 5 weeks pregnant, and only have swollen breasts and I'm tired. I'm worried bc I am having cramping. I hear that this is normal. There isn't any blood. I sometimes don't "feel " pregnant at all. I so badly want this baby, and my friend just had a miscarriage at 6 weeks which makes me super worried and paranoid ! I keep trying to tell myself, "Renee, you've never been pregnant before, every pregnancy is different, relax." But it's so hard not to think about it. Is this normal ? Am I having normal symptoms? Thank you for your feedback !!!! Xoxoxo
