Lovenox and Breastfeeding

I gave birth to my child and a week later found out I had at blood clot in my leg. They have me taking Lovenox shots twice a day, I am currently breastfeeding and the doctors told me that lovenox is okay to take while breastfeeding because it is considered an L2 medication. I’m just a little worried l, is anyone else nursing while on Lovenox?
