I need a bit of help!

Okay today I had this weird pain in my stumic, It would come and go about every 20 mins. It got so bad at times I would be bent over in pain. I also spotted during this pain just a couple drops of blood then be done. It lasted about 3 hrs then hasn't happend again. Just a little sore around my ovaries that's it. I'm not to far off of my ovulation just wondering would could have it been that cuased the pain? I need a bit of help lady's if u could. Thank you ?
