I had surgical management for an MMC 5 weeks ago, I was testing occasionally until I got what I thought was a negative pregnancy test. I started doing OPKs and got a positive one 12 days ago, my LP is usually 10 days so I thought I’d take a test just to check since AF hasn’t arrived yet & I got this… could this be the start of a new pregnancy or still leftover HCG from the last? I know time will tell but curious for opinions, thanks!
