Ok so the more I think about it the more I'm worried. I had my last period jan 8th. Before my boys my cycles were only 25 days. I had some cramping about a week after my AF so I thought it was me ovulating and of course my dumb self let my DH talk me into having sex that next night. About 3 or 4 nights ago I thought I had a bladder infection, that's what I convinced myself it was. I was doubled over in pain for about an hour, then light cramping for maybe a day or so. Now that I'm thinking about it could that have been implantation? I had slight implantation cramping with my youngest but not like that.
