constant acid reflux.. is this an early sign?

[MrsPhillips]

Well I am 4DPO and been feeling 'different' but especially since 3am this morning I have had constant acid reflux in my throat that I can't get to shift. I have only ever had this once before in my life years ago but didnt last longer than an hour. Could this be a sign, has anyone else had this after ovulation? My boobs have been swollen since yesterday and sore too.

I'm keeping everything crossed. What do you think Ladies? -x-
