Pregnancy after 4 MC

So, my husband and I have been trying 2 years. I have 2 and he has 1 from a previous relationship.

We have had 4 MC since starting to try, two chemical and 2 before 10 weeks. I just got another positive pregnancy test today...I just don't know how I feel. I honestly am so worried that it's going to end the same way. I was starting to come to accept that we probably would just stop trying to conceive and was researching tubal ligation the other day.

It is not that I changed my mind about having a baby, just that my heart is having such a hard time taking all of this loss. And to purposely put ourselves in the position to lose again is just hard.

I can't get attached, I can't get excited. We are both trying to be hopeful but also just waiting for bad news. Anyone else feeling this?
