Tomorrow I am starting my progesterone shots and this is an instruction that Lori wrote me: You will use your 3ml syringe and the 18g 1 ½” needle to draw up the 2 ml’s of the oil. Then take that needle off and replace it with the 22g 11/2” needle to give your injection. However, in accordance with the description on my package that I have been sent from MDR, there are different syringes, 25g with the light blue cap. And I have just very few 18g (pink caps). Those that used progesterone injections, could you write me your experiences? I mean which needles did you use?
