Ahh I think it's natural to be scared! I'm scared after having had 2 miscarriages and being just over 6 weeks pregnant.
I'm half expecting to start bleeding constantly and over analysing to make sure I have some symptoms
My symptoms have been pretty mild from nausea, tiredness but the constant symptom being cramps every couple hours.
My tactic is just keeping myself busy and sometimes letting myself feel what I want to feel as from what I gather pregnancy is a rollercoaster and some peoples rollercoaster ride involves a lot more loops especially after a miscarriage!
Hope that's some comfort to you x
