Pregnant before first period after miscarriage

Elisabeth
I miscarried at 5 weeks on November 24th. I saw my doctor and he said we were fine to start trying again and next cycle I should track for him. He said if we got pregnant before my first cycle it wouldn't be a problem especially because my hcg level was back to almost 0 but we were still planning to wait one cycle. We weren't preventing but weren't trying and we honestly didn't have sex much at all. So yesterday since I still hadn't started I took a test just to be sure I wasn't and all 4 tests were very positive. So obviously we are extremely excited and nervous. Anyone else have similar experiences??
