Mirena and symptoms?

I'm not sure what to do.  I have chronic constipation and an intermittent intsuseption.  These plus ulcers mean that I'm used to having nauseau from time to time, and for the last few days I've had nauseau every day which is not normal.   I can't eat as much at one time as I usually do, but I'm hungry more frequently.  My breast were almost flat from the weight loss, and the last few days I feel like they are bigger than they have been in a long time.  Last night and today I am crampy and bloated in my belly. 

My mirena is turning 3 this August and I've not been sexually active in my life until the last month.  I am even thinking about ttc next spring when we've been together a little longer if it works out.  But I am not ready yet.  And now I've been reading about all these women who have had unexpected pregnancies with Mirena.  I just had my 2 year blood work and I know that I'm low on iron and D.  I don't know about folic, or dha, and I have a mirena IUD sitting in there that I'm learning can cause a miscarrage, or can be pulled causeing a miscarrage, or can be left and may or may not cause problems with the fetus. 

The other thing is I really am not ready yet!!  I want to be a mommy but not when we've only been together for 3 months!

My "Mirena baby" just turned 3 months old yesterday. I had a perfectly inserted IUD and still got pregnant. No birth crontrol is 100%, even an IUD can fail.
Go buy a pregnancy test! 

The sooner you know for sure, the better.

Ok, I'm having a blood test after I leave school tonight.  Called my GYN and she agreed that I should take a test, said I could take one at home but that if it was negative she would suggest I take the blood test and I said I didn't want to wait, that i wouldn't be satisfied to wait again if the home test was negative.  I am was going into town tonight, could I take the blood test tonight.  She's sending the request to the lab, but she won't have the answer till tomorrow. 

She asked if she could call me and since I'm teaching in several classrooms (I'm a special educator who pushing into other rooms all morning) I told her to leave me a message.  She asked if I wanted her to be blunt or soft pedal and I said just be blunt I need to know so I don't keep panicing.

I'm not sure if I want to ask for prayers for a positive or a negative.  This is something I wasn't sure would ever happen, but it is really too soon in this relationship.  I will do everything in my power to keep it if I am, but omg, I don't think I'm ready.
