sex after birth

i gave birth 5 weeks, 1 day ago. we started having sex again on june 22, which was 2 weeks ago. he pulled out every time until just a few days ago, he started finishing in me again. i took plan b the day after it happened the first time and then that night he did it again. is there a chance i could get pregnant again this soon or should i not worry since i might not have ovulated yet? im breastfeeding so i dont know when my period is going to end up starting. i dont have a problem having another baby, i just dont want it to be this soon as my body hasnt even healed from giving birth on june 1.
