I have two swollen lymph nodes on both sides of my groin. They started to swell on Saturday after I had sex. Then they started to actually hurt on Monday now they don't really hurt anymore. Also the right swollen lymph node's swelling is going down and doesn't hurt at all but my left one is pretty big and is started to hurt again! I thought I had a STD but I have none of the listed symptoms except for swelling. I'm bloating, cramping REALLY bad, and gassy. I've also been on the depo shot for 5 months and I've got all my shot on time. Could I possibly be pregnant? My body is freaking me out. Help.
