What does implantation feel like?

Jenny
First of all I did have the depo shot about 2 1/2 months ago and am due for another one July 7th. I have somewhat normal periods the only thing that changed after I had my first shot was the time my period starts seems to be around the same time of the month when I had recived the shot. When my period ended this month I noticed a discharge like I was ovulating but didn't think anything of it, my husband and I had sex the next day this was about a week ago and since then we've had sex 4 other times. This evening I've been feeling a pinching sensation in lowest part of my abdomen like where it would hurt if I was having period cramps but this is different it doesn't really hurt but it feels like light pinching...could this be implantation? I don't have any bleeding and I plan on testing first thing tomorrow morning...I've just never felt this before and the only thing we are doing to prevent pregnancy is the depo shot. I would be happy if I was pregnant we just weren't planning on having children this soon. Sorry this so long...and I appreciate any one who can give me some input! 😊
