lonely and worried while I'm waiting to share news

I had a miscarriage in mid December (only about 5 weeks in, actually only knew I was pregnant for less than a week), and then got pregnant again pretty quick after (no period in between).

Now I'm on week 6, and today I had a little spotting. I know it can be normal, but it still kind of freaks me out. We haven't told anybody about this pregnancy (and didn't during the other one either).

My hubs has been really supportive and wonderful, but I'm still feeling really alone right now going through the worry about having another mc. He's here for me 100%, but I'm the one who is currently dreading going pee because of whatever may happen next. I have been "following the rules" and I know that even if another mc happens, it's not my fault... but it's still so damn nervy.

Dr appointment (first one) isn't till the 22nd. Any words of encouragement or comfort are welcome. :(
