Help advise x

Me and my long term partner are trying for a baby, for over a year and no luck until last May we found out we were expecting but unfortunately had a miscarriage a week after we found out. We waited a few cycles as the doctor recommended and we are trying again. After a miscarriage does this mean there's more chance for me getting pregnant easier? Also I've been feeling sicky for a few weeks. Sicky feeling, and gone off apatite. Which is unlike me cause I'm a big foody! It's now one day before my period and I've got thick white milky discharge and tender breasts... Could this be a possibility?
