I need help figuring out what’s going on....

Emily

Me and my husband are ttc baby number 2. The past 3 days I’ve had terrible hot flashes, my fingers have been getting super swollen throughout the day, with back pain and cramps in my stomach. I know people will just say take a test but I did about 5 days ago and I’m pretty sure it was just a evap line[ill post a pic] also I’m not 100% sure when I ovulated this moth I tired to use OPKs but got confusing results. On Thursday i got really bad left side cramps and a dull pain just on the side I’m thinking I may have ovulated then... any ideas???

Also on Thursday I have white watery CM.... could the swelling, back pain, and cramps be implantation or is it too soon if I ovulated Thursday??
