Can you feel anything during conception?

I think i have ovulated on the 20, 21, and 22 of this month. On the 21st i found some stretchy, jelly, and squishy like discharge. It was in a big bundle though. I guess that means i was very fertile or something. So i had on the 22nd. He didnt came in me or anything. We used the pull-out method. The day after that, i had some slight crampings ever since. I feel so hungry, but this could be a sign that im getting my period. But right now my periods are all over the place because i have just gotten off the Depo shot. Ive only been on the shot one time. I think i had 2 periods last month. And this month seems to be regular. Im still waiting on my period. I dont get it until the 1st of September. So i was wondering if the slight cramps were a sign of conceptions? Im a little confuse. And omg, i been having some weird dreams about me being pregnant, or me having a baby. I think im tripping out.
