A.,
Congratulations on breastfeeding your baby girl! You are doing the best thing for her!
Don't give up!
How did the tea make you sick?
If you haven't gotten the reply already: try Fenugreek & Blessed thistle together. They work better in tandem. Follow the instructions.
If after a couple of days those don't work (and I would contact your OB first to get the script just in case) there is a med out there for something else that has a side effect of increasing milk flow.
Also make sure your vitamins are on the + side. Don't over do them, but make sure you're getting enough for you.
I suggest getting the script from the OB (I'm sorry I can't remember the name of the med) beforehand because sometimes it can take a while to either get the appointment or just get their attention, and if you wait days or weeks to see the OB, you will only feel more frustrated - which is stress too - and feel like your baby is losing out (more stress).
I felt the same way - around 5-6 months though! I still have that feeling that I don't give enough milk to my son.
One thing I discovered was: drinking during nursing helps a lot! My son will finish on one side, then want the other, and by the time he's done there, will be ready to go back to the first side (sometimes we go back and forth 2-3 times) and there will be enough for him to drink.
Good luck, and I hope you have time to let me know how things go!
