Pregnant?

Kirbi
​I'm 3 days late for my period. Past few weeks I have suspected pregnancy. Moody, very crampy tender breasts, a complete depletion of my milk supply, headaches and diarrhea. Did have sex on ovulation day and before and after. My first child is 9 months old. 
Is this my bfp?!!! 
​Also, I had a csection with my first child and am hoping to do a home birth vbac. Would love any success stories and some positive energy!!! I'm scared to death to go through the birthing process again! My last experience was traumatic!
