Is it true?

My miscarriage bleeding just ended 2 weeks ago. We haven't bd much since then but maybe like 5ish times. My friend said I could be pregnant already. I had a really tiny amout of blood come on the tp the other night, she doesn't know it lol. Could you really get pregnant that soon? It kind of worries me tbh my body probably hasn't healed yet. I was almost 6 weeks.
