I feel preggo but I'm not sure...

Stephanie
The paranoia is getting to me and this month is so awkward, I'm not sure if my stressed made my cycle start early or if implantation started late and my "period" happened anyways.... 
​I've got sore breasts, fatigue and random nausea, cravings and cramping, everything I felt with my first but it looks like I started my period today. My uterus has been puffy for a week and feels almost hard to the touch. 
​I was going to test Thursday when my period was due (if I was late) but then I started bleeding today and now I'm not sure, I'm usually a heavy flow and it's much lighter than normal.
​Anyone ever have this or anything similar? Suggestions, ladies? Thanks for reading!
