perhaps you had a muscle ache. Sometimes, when you are trying to get pregnant, you become hyperaware of your body, and the minor aches and pulls that come naturally but are ignored. Currently, I have an ache in near my diaphragm. Usually I would ignore it, but now because of you, I am aware. Oh, wait..it went away.
Minor aches and pains happen all the time.
" oh. and I can always feel when I ovulate so why wouldn't I feel conception?"
Yes, mittelschmertz, I think it's called. Ovulation involves actual muscles and internal organs. A sperm and an egg does not have nerve endings. It's about as sensible as saying that you can feel one of your cells divide.
