Trying to get pregnant!

Erika

So me and my husband have been trying to have a baby!! And I got my Mirena our Dec. 12 and my dr told me to take a test in 2 weeks cuz I would most likely be pregnant especially if we are actively trying. I took one and it was negative. The last week or so I have been horrible cramps and like a sharp stabbing pain in my vaginal area kinda like in my cervix, I’ve also been light headed and nauseas all the time. I haven’t started my period and I would have usually started by the 20th but I didn’t have a period while on Mirena. Anyone else experice this and what was your out come of it?
