Will breastfeeding mimic a pregnancy? My daughter is 13 months old and I thought for sure I was pregnant but I had a urine test at the doc last week and it proved negative. I feel pregnant and have a tummy! So again, should I be feeling pregnant if I'm not? I have all the pregnancy symptoms; tired once a day, urinating more, indigestion, backache and headache but a negative test! Oh and I have been feeling flutters but I guess that could be ovulation? I'd appreciate any thoughts Thanks.
