Not sure what category/tmi

Alissa • Expecting baby #1 in December and we couldn't be any more excited!♡
I ended my last period on the 20th of this month and for the past three days have had light spotting(ranging from red to dark brown),stomach cramps, and normal cramps. I've had more bowel movements lately(sorry just didn't know if that info would be useful), and I feel slightly nauseous for a little bit then it goes away. My fiancé and I have been ttc for over a year and I have started to lose hope. Not sure if this is leftover blood from my previous period or what
