Leaking milk..after drying up..& Paragaurd

Okay..so I EP for 6 weeks then dried up my milk after getting an infection for a second time. My first period ended the day I was 8 weeks PP. I got my birth control put in 10 weeks PP, but we used condoms before & waited a week to have sex after I got the Paragaurd IUD put in. I bled like crazy for maybe a week with bad cramps. Then stopped for a week. Then bled for another 5 days (12/21-12/25) According to glow my period was suppose to start Saturday (12/26) no period..can't figure out if the bleeding earlier on was suppose to be my period of from the BC again..I'm going to be watching for cervical mucus to see if I ovulate so I'll know for sure, but anyway I wanted to know others experiences with the paragaurd. & I found it odd that lately I can't stay awake past 10pm..I feel extremely hungry even after I've just eaten (just like early pregnancy with my daughter), oddly cold (again like previous pregnancy), & I just randomly started leaking milk from both breasts..I have no idea what's going on although I've read it's possible to leak even years later..no sore nipples like before (although different pregnancies can vary & be completely different then the rest). I have an appointment on Jan 8th with my ob. She scheduled it when she put my bc in. She said to come back so she could make sure it's in place like it should be..we did have sex a couple times around ovulation..but like I said we used birth control. Maybe I should test in a few days? I'm just freaked because I don't want to be pregnant again especially since my daughter was concieved a year ago..
