sex and pregnancy after miscarriage

Hi all, looking for some help and advice please. I miscarried on Tuesday the 23rd of last month and bleeding had completely stopped by the 27th. I was around 6-7 weeks. We started having unprotected sex the day after I stopped bleeding and have been at least once a day since then. Also my fertile days this month are almost at an end and we've had sex on every one of the days. What are the chances of getting pregnant straight away after a mc? I have virtually no information and I'm desperate to conceive again! Thanks. X
