Hi, i had a baby 17 weeks ago and for the past 6 weeks i've had a fluttery empty feeling in my stomach, hungry all the time, fuller breasts (bigg then when i was pregnate and breast feeding) weeing all the time and can't lay on my tummy. i've done 4 preg test they have all come back neg! i had a "period" last week but it was very abnormal, it was never enough to fill a pad and it was manily when i wiped my self after weeing, i also suffer from PCOS. what could be happening? i've seen 2 doctors about this and they say not to worry but the fact of the matter is I AM.......
