I have been in both places

(three actually) I have been unmarried and pregnant and not even known who the father of the baby was (that's a horrifying thing to have to tell your daddy). I have been involved with a guy- and we even got married before the baby- and given the baby up for adoption. (We got divorced about a year after we were married--unrelated to the baby being placed up for adoption) And I have been involved with a guy- got pregnant, kept the baby- and married the dad about two years after our son was born. We are still together and have four children and one on the way. I don't think my husband ever really thought that he would have children--though he wasn't dead set against it, either.
First of all God bless you for not just aborting your sweet baby! That is an immense grace

Secondly- CONGRATULATIONS!!!! What a blessing that God has created with your cooperation this new soul, this new being created in His image and likeness!
Only you will be able to discern the right course of action for you to take. And you will only be able to discern that through heartfelt, all out prayer. I absolutely second the recommendation for counselling. Free (or VERY inexpensive) counselling should be available to you through Catholic Social services--or through your diocesan office of family life. The pastor- or someone in the office (see if there is either a pro-life ministry or Project Gabriel at your parish)- should be able to direct you as to how to contact those agencies. They will have help to offer you!
The thing to really focus in on is what decision leaves you with the most peace. I have found in making big decisions, that peace of soul is usually the best indicator of what I ought to chose--even if all options involve struggle and sacrifice.
Maybe this pregnancy and child is God's way of calling you back to Him...I know it really was for me with the children I gave up for adoption (though I was still too broken and wounded to respond fully to that call)--and especially in the case of my husband and my oldest son. That little boy's birth and nursing and my motherhood was the impetus for much, much healing - which enable me to begin to accept the immensity of God's love. My husband is still an aetheist-- and yet is so supportive, so nurturing of not only my faith life- but also of me passing the faith on to our children. I don't know how that came about except through the incerdible perfections of God. And my deep and vulnerable step out in faith -- to cast my net into deep waters-- began with being a mom to my son. I actually didn't really even know how broken I was...but there was a reason I ended up pregnant (again

) outside of marriage. I longed and ached and yearned for love--and felt totally unable to give love and be loved becuase of how broken and wounded I was-- through the actions of others, my own sins, and mental strife from some of those things. Healing for me has and is a hard road....but I have no doubt about where and when I began to travel that road- it was the birth of our oldest son- and the beginning of our family.
It turns out that my husband is wild about his kids- and is so ridiculously open to life (especially considering is a pro-choice aetheist)--because he sees that more than anything else in the entire world- his children bring him joy. Yes they are lots of work, and a pain in the rear, and challenging beyond imagination-- but deep inside he experiences that healing power of God giving love and calling us to give love profoundly through his children. When my husband held our son for the first time-- he was hooked....he fell madly in love.
We have had our ups and downs-- we have had some seriously stressful and bad times-- but the joy and peace I feel today- and the love through my husband that I experience today--is so much greater than any that I ever thought I would know. And for us it is all still beginning...it is exciting knowing that there is even more love to experience. It has not been easy- at times I thought it would all kill me for sure- I am not a "natural" mother-- motherhood for me comes with a lot of work and struggle. I am not even a very good wife....but I am so grateful for it all---even, if not especially for the suffering--because it has given me endurance, and compassion, and kindness and hope...that I never would have without the blessed gift of suffering.
Plaese know that you can PM me anytime...or ask me any questions here--about adoption or about keeping your baby---or even just to talk about the wierd mix of emotions- fear and excitement and everything all jumbled.
You all have my prayers
