Late period but Bfn

shannon

So according to glow im 2 days late and according to flo im 5 - but ive taken a pregnancy test and it was BfN :( Do you think there still could be a chance im pregnant and just have low HCG levels?

I have sore nipples, smells make me sick, heart burn ( which ive never had before ) weird pulling cramps and real mood swings and white creamy CM ( no odour )

I hate not knowing.
