I already counted the omer without a bracha the day before. The following evening I again forgot to count but did count with a bracha that night between zman talit and sunrise. Can I continue to count with a bracha?

Shalom, Thank you for your question. I am not sure if I fully understand what you did – but it seems that you counted on every day, and may continue to count with a blessing. Even if you forgot to count in the evening, if you counted during the day (and all the more so before sunrise), then you did not miss a complete day of counting, and continue counting with a blessing. Blessings.
