I'd say it's not very likely that you're pregnant. It's possible, but not likely at all. I personally wouldn't test unless I had some other pregnancy indicators. For the first year after I had my dd, I drove myself crazy thinking I had ovulated and conceived. I didn't end up getting ppaf until 21 months pp, yet I took tests at 4, 5, and 6 months pp. I even believed I was getting morning sickness. Maybe I'm just loony!
You did have the 7 weeks pp bleeding, but as your midwife suggested, I think it's likely it was just the last of the pp blood. Still, it has happened before, so if you feel you must, TEST!
