Hi. Im just wonering how early pregnancy symptoms can start. Lately ive been pretty irregular with my periods, anywhere from 28 to 35 days, and on day 19 now. I have been experiencing all day nausea , thrown up once but a lot gagging, my breasts and nipples are very sore and even hurt when im just walking. Im wondering if my hormones are just going out of wack due to the irregular periods or if i could potentially be pregnant. Im a labor and delivery nurse so my mind is on babies almost 100 percent of the time but these symtpoms arent my usual pms symptoms so i was just curious if these symptoms could be too early for a pregnancy. Thanks so much :)
