I'm 9 weeks pregnant from my last missed period. Had positive tests plus some nausea, very emotional and have gone off certain foods. My son is 8 months old so I'm pregnant quite quickly but I'm worried as with both my other pregnancies I had morning sickness, sore boobs and felt pretty unwell. This time I haven't got sore boobs, they don't seem to appear any bigger or have pronounced veins. I don't have a brown line down my tummy and apart from being emotional and feeling some nausea I actually feel okay. Could this be because it's 3rd baby and my last pregnancy wasn't long ago and my body is more used to the hormones or should I be worried?
