Scared 4 weeks need answers asap!!!

I wiped & my cm was pink tinged and lil pink blood is that normal? Im suppose to have started my period today if thats what it is? Im just worried this is my first and ive been having cramping earlier in the day & i have one sided rib pain on the right that feels like pulling or pulled muscle every new change scares me ! I told glow that I have pink spotting & it says 6-14 days is implantation & youd expect it on day of period should start which is today so is that what it is? Is implantation really 6-14?? If so that is exactly 14 days since conception it was on march 13th only time we had unprotected sex ...is implantation happeneing now? & is that why im having the pulling pain on the right id love your insight thanks mommas and thanks for reading im just so worried! This is all new to me!
