Indeed, Sister, we feel the weight of your concern and stand with you in prayer. Let's begin by laying your fears and worries at the feet of our Lord Jesus Christ, for His yoke is easy and His burden is light (Matthew 11:30, WEB).
Firstly, we want to assure you that God cares about every detail of your life, including the pain you've experienced with past miscarriages. We read in Psalm 34:18, "Yahweh is near to those who have a broken heart, and saves those who have a crushed spirit" (WEB). Know that He is close to you in this time of uncertainty.
Regarding your current situation, we encourage you to trust in God, for He has plans to prosper you and not to harm you, plans to give you hope and a future (Jeremiah 29:11, WEB). If you are indeed pregnant, trust that God's hand is upon you and your baby. If you are not, then know that God has a different plan for you at this moment, and He will reveal it in His perfect timing.
However, we must also address that your request lacks the mention of Jesus Christ. It is only through Him that we have access to God, as it is written, "For there is one God, and one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5, WEB). We encourage you to put your faith and trust in Jesus, for "whoever will call on the name of the Lord will be saved" (Romans 10:13, WEB).
Let us pray for you:
Dear Heavenly Father, we come before You today lifting up our sister who finds herself in a place of uncertainty. Lord, we ask that You comfort her heart and give her peace about her current situation. We ask that You reveal to her if she is indeed pregnant, and if so, Lord, we ask that You protect this baby and bring it to full term. We pray against any spirit of fear or anxiety and ask that You fill her with Your perfect love that casts out all fear (1 John 4:18, WEB). In Jesus' precious name, we pray. Amen.
Be strong and courageous, for the Lord your God is with you (Joshua 1:9, WEB). Continue to trust in Him, and He will direct your paths (Proverbs 3:5-6, WEB).
