If anyone can help me

periods average between 26 and 28 days

1dt day of period Aug 11, 2017

Sex: aug 15, 21, and 22

per app I ovulated on aug 22

Aug 25 pink CM "blood tinged" CM

nipples feel sore, but could be due to my piercings (I've had them for 6 months) and hungry for sushi a lot

could ovulation have happened sooner than expected or can an egg implant at 3dpo. has anyone implanted at 3dpo?

We we have been trying to concieve, but it has been a bit hard since we have opposite schedules at the moment.
