Hey! I've posted numerous threads about this--- I just need to be sure. Can someone explain this? Fertile? Developing? What's that dot? I can see... Veins? It's hard to see the veins on the photos. Ignore the pen, I made the idiotic mistake of using one instead of a pencil. There is a black dot...? Here shows the air bubble but it isn't very visible on this photo Please help me! Thank you!!!!!!!
