Implantation tmi no pic

Megan • Trying for our third! First baby a miscarriage, chemical then rainbow. Second baby 9 months of trying 4 with clomid. Hoping for a quick easy pregnancy for #3
On 4 dpo I believe I had diarrhea, cramping nausea in the morning and later noticed just a little bigger then a pencil tip of blood on my underwear, I know it's early but could this have been implantation I also had a mini temp dip and later went up to 98
