Pregnant with #2

I’m 5 weeks along with baby #2 and I have NO symptoms!!! I miscarried my first at 9 weeks which I didn’t have any symptoms with. My boobs/nipples were sensitive at the beginning with my now 11 month old. Never had morning sickness. I’m nervous about this one. My lines on my hpt are getting darker. I know every pregnancy is different and 5 weeks is still a little too early but I can’t help think the worse. Any mommas have no symptoms and have healthy babies??
