wow thats a tough one! I didn't have implantation spotting but I did spot alot in my first trimester. I know how spotting can mess with your mind

If you had it with your first one then you may be prone to it again. I am just wondering if you would have such strong symptoms before you implanted? ( I don't know - just wondering

)
I hate to say this but I think only time will tell. Waiting is so hard! At least you will know tomorrow! Good luck- tons of baby vibes to you!
