Yes, there are physical sym...well I wouldn't call them "symptoms", but subtle changes that are extremely hard for the conscious mind to pickup on but the subconscious mind, especially in males, do in deed notice, we just don't know that we notice. When you're ovulating your cheeks and lips are a bit rosier (which is why females wear makeup, to make it look like they're ovulating, even if they aren't aware of it). There's even a change in your voice that we don't realize that we're hearing. There was a show on Discovery about this, they had a group of guys look at two pictures of the same women, one taken when she was ovulating and one taken when she wasn't, you could NOT tell the difference, they didn't tell them what the experiment was, but the men ALL agreed the ovulating picture looked prettier! They had the men listen to two voice recordings, the same woman, and the results were the same. They said the ovulating one sounded sexier.
Cramping, and if you have a regular-heavy flow (just not extremely light) then you will probably be able to feel the blood dripping out, it doesn't hurt, just an uncomfortable feeling, and you would only feel it if you were not wearing a tampon
Yup, my friend has that. Very few women can physically feel it happening, but from what I hear from my friend it feels like someone is stabbing you in the ovary before your period actually starts. It's a different pain from cramps, it hurts more. She found this out by talking to her dr about it. :)
