hello me and my husband have been trying to conceive for about a year we were both tested and everything was normal. which put our mind at ease and i was calculating my cycle which ranges from 27-29 days. For the past few days i have been feeling nauseous (vomited a few times) before and after i eat, very tired at odd times of the day, sore nipples, lower back pains, and an odd feeling in my stomach(i am not a big girl) so i notice very much when i am bloated this doesn't feel the same my stomach is hard and i feel when i sit down it cuts the breath. when i talk or go up the stairs i get really shortness of breath( i walk twice a day on reg. basis) and i haven't been able to lately. this is the 3rd child (youngest is 8) and i can't remember how it was at first during the other 2 pregnancies. Are these sign of pregnancy i will be late for my period as of Nov.11
