Tips/ideas

Has anyone got any tips or ideas on how to get pregnant? I sadly lost a baby in February and have been trying since. All the negative tests are just so crap 😩😢! I’ve tried recording my ovulation and period charts, I’ve tried taking folic acid and vitamin d. Have been sex every other day during the fertile window obviously. Tried to put on weight slowly which seems to be going well but it’s hard when I’ve got a high metabolism and it says to eat healthy. Anything else I can do?
