Ttc post miscarriage

Hi all. We’ve been ttc since we got married at the end of July. Caught in august, miscarried in october, depressed through November so this is our next chance. The app says I’m ovulating on 1 January but I’ve been having small cramps all day so wondering if I’m ovulating now? We are doing the whole have sex everyday game and not using bbt or ovulation kits yet as don’t want it to take over our lives.
