I am 6 weeks w. my second pregnancy too. Till yet didn't notice any different symptoms than the first. Let see. I am curious also to see if it will be similar to the first or different in term of symptoms.
I'm also 8 weeks with my second baby and this pregnancy is really different to my first. I'm experience horrendous back ache which I only experienced in the last month of my last pregnancy. My last pregnancy I only really had cramping with 1 day of sickness. This time it's headaches, tiredness, constipation, nausea and backache. I think with the headache and tiredness it's probs because have a young toddler to run after all day
