Milk supply & pregnancy??

For those of you who got pregnant again right away did you notice any change in your milk supply right away? Backstory: Ever since my LO was born I have EBF (now 15 weeks old). I had my first period 6 weeks PP, the second followed 31 days later. My milk supply would normally decrease the week before I started. It did the same this time around for me to be on track except now I’m 34 days out and my milk supply has decreased even more than usual (during my morning pump session). I have been under a lot of stress lately and to add to it now I’m worried about being pregnant again 😭
