anyone found it harder to conceive after their miscarraige

Hi I have 2 kids to my previous partner ages 10 and 6 I was pregnant within 3 cycles with both . me and my husband decided to try in May fell pregnant again on 3rd cycle September had d&c; for Mmc had a faint positive last week 4th cycle but then a negative and period turned up as normal so this is now my 5th cycle since my miscarriage. I'm really starting to give up and I'm so depressed I just keep thinking the baby we lost is the only baby we'll ever get close to having
