Implantation bleed????

Ellie

Hi ladies, so been trying for another buddle of joy for 11 months now I have a 30 day cycle my period is due in 7 days so 3 days ago I started having really light spotting was more like a pink/brown discharge its not even enough to put a pad on. Only little cramps. The spotting lasted 2 days and then nothing and then on the 3rd day had a little bit more but was more brown this time. I am extremely nauseas I have even had to take a couple days off work now as I work round food everything is knocking me sick to my stomach. Anyone experience implantation bleed before and could this be it for me. So anxious. Xx
