Remove whitespace before the_excerpt();

I need to delete the whitespace that the_excerpt(); function returns me. I noticed it gives me whitespace before the whole text only where in the page images goes first and only after goes text.

I tried str_replace(); and trim(); none of them helped.

This is caused by the line break between the first image in the post and the body content of the post. Just delete the one line of space between the two and it will working fine.
