I am confused- please help

Marina
Hi all, 
A couple of days ago I found out I'm almost 5 weeks pregnant and to be honest I'm all over the place. 
I've been reading and you all seem to be over the moon with the pregnancies, unfortunately that's not my case. 
I'm sad, very sad, I'm  so confused and I have been asking myself all kind of questions. I don't think I've ever had the motherly thing. Up until 1 year ago having children wasn't one of my priorities. Then I found out my AMH levels are super low and my world was turned upside down. Maybe the fact that the choice was being removed sparked something inside me, like being in a hurry to try. It took a year for me and my partner to decide to stop using condom because none of us were comfortable with the idea. Finally January 2017 we had sex without protection thinking that because I'm almost without eggs this process was going to be long etc, guess what, it wasn't. 
Now I'm super emotional, all I want to do is cry, I feel weird, I am embarrassed with telling people I'm pregnant. I'm scared that I made the wrong decision, I'm scared I won't be able to be happy with this baby, it stills doesn't feel a part of me... maybe we should've waited longer but maybe this is my only chance...
Anyone else experienced something similar that can give me some advice? 
Thanking you from the bottom of my heart ❤
