Really nervous

4w2d with my second baby and I’m so nervous! I have no idea why, first baby I peed on ONE STICK and that was it. I have no done about 20 no joke (I have the cheap strips so just all the time lol) and I’m worried about miscarriage so much. I think just from these forums. I never realised just how common it was , now I do and think it’ll happen to me! I had my blood test yesterday and will get results tomorrow. But my veins are so shitty I don’t want to get any more unless for some reason so I won’t know if they’ve risen! Then I’m worried I’ll have a scan at 7 weeks and there be nothing!

I just can’t believe I’m pregnant! Lol
