Positive test after miscarriage! 🙄

My last pregnancy ended at 10 weeks😥, Since then has been 2 weeks and i keep getting strong positive tests, I suppose to ovulate soon but there is no way of me knowing. I’ve heard stories where I supposed to wait at least 1 cycle to start trying again, but on the other hand some of my friends didn’t wait at all...

So my question to you ladys is:

How long the positive test kept showing up after you had miscarriage?? And any of you got pregnant right away without waiting?

TIA
