Ovulation After Miscarriage

Sarah
Hi Ladies, 
I Had my Son on the 14th April this year at 24 weeks.. Of course he had died in the womb before I had him.. 😞
I'm just wondering if any of you ladies have shared a similar experience as my ovulation since then hasn't been great.. Before I would ovulate for 4 days but now I'm lucky if I get 1 day a month.. Does anyone have any advice? Would be greatly appreciated.. Thank you in advance
