keep an eye out for migraines, pain in upper belly (more right side) swelling, and if you have a raised blood pressure, just to be on the safe side could be pre-eclampsia, i never got morning sickness in the first three months i suffered more after 20 weeks and a slow develop of those syptoms which i then ended up with sevre eclampsia my baby was delivered at 31 weeks 5 days so just make sure to tell your midwife/doctor and ask for a blood pressure check to ease ur mind, good luck hope it goes
