Milk supply


This may be a bit long so please bear with me. So my baby is one week old today. While in the hospital I had to formula feed as well as breast because she wasn't peeing... so I continued with the formula and breast since I wasn't producing much yet... I had to get a blood patch due to horrible headaches from the spinal from my c section.... during the few days of horrible headaches I wasn't putting her to my breast or pumping much..... she is getting a little while on my breast but I don't think much and when I pumped last night hardly anything came out.... so my question is is it too late to build

Up my supply? Have I missed my window of opportunity? I see horrible like I should have just endured the pain and pumped through the headaches anyway. Can anyone please help with some advice! If you've read all of his then thank you!!
