Could this be my postpartum period

I am 7 weeks postpartum. I stopped pumping 3 weeks ago. 5 and a half weeks postpartum hubby and I did the deed he didn’t pull out yes I know that was a big no no. Yesterday was 10 days since we did the deed I thought I was starting my postpartum period i also got vaginal pain like I do when I start my periods. I noticed light pink spotting when I wiped with toilet paper. Then i had what looked like a string of brown blood now the spotting went away. Along with nipple pain. So I’m not sure if this is a start of my postpartum period or if it’s implantation spotting. The day after we did the deed I noticed what looked like egg white cm.
