Lactating on Paragard

Regina • 21.FL in love
I woke up this morning and did my normal morning routine, and when I stopped to get dressed I saw that around my nipples were wet on my bathrobe. I laughed it off and took it off and did a squeeze of each side to check, and liquid came out of my left breast. I work in an infant classroom and I'm very familiar with breast milk, this was breast milk. I've had the Paragard IUD for four to five months now, and my SO for the first time starting cumming in me. Having an IUD made me not nervous about pregnancy whatsoever until now. I'm going to urgent are and requesting a pregnancy test-- but has anyone else ever experienced this? My SO is about to move to Korea for a year to teach and I am NOT ready to raise a child on my own.
