Unfounded fears

i think unfounded fear is worse than false hope. Sometimes, if i let my mind go there, it will start trying to convince me that not only am i not going to become pregnant this month, it won't happen next month or any following month either...This fear that as strong as this desire to become a mother is- it is not gonna happen. i hate it cuz i know it is not from God, who i know has placed this on my heart and completely transformed my mind and gotten rid of a lot of selfishness in me. Stuff that really i would never have been willing to let go on my own. Also, so much is going so well right now, it just seems like God is pulling it all together. So why do i worry? Well it is not constant, just a little piercing thought that works its way in once in a while, and if i allow it to grows into something much worse. Abba, protect my mind and heart from this fear. Fill me with Your peace, that You do not start something and not follow through. You have always given me the best, and help me not to doubt what You have done and are doing in me right now. Please fill me with peace and hope, and knit together in my womb a beautiful child that we can raise to love You and do Your work.
