This first day of my last period was nov. 16 .

On November 23/around 11pm we had intercorse .

on the 25th around 10ish pm during intercorse this time there was a bit of mucus and Brown blood mixture , enough for him to ask me if I wAs getting my period again ..

After that it stopped and only when I wiped was a Few spotting here and there .. drops of blood and mixed with clear stretchy mucus discharge ... lasted 2 full days like that off and on . Along with some mild cramping .

But accourding to my calendar I was still 4/5 days from my actual O day .

Is it possible that I ovulated early ??? Could this be implatation ?? Or could it just be a crazy ovulation symptom ..??? Never has this happened before , even with my last pregnancy .

16 days before expected period ...

What do you ladies think????????
