TTC after stillbirth....

Hi all! New to this...my daughter was born asleep @39wks back in January of this year....hugely devastating. She was my 2nd. I have an 8 year old son too...so currently trying to get pregnant again for the third and final time. Would love my rainbow baby....has anyone found it hard to conceive after a stillbirth?! Not happening as fast as I thought...my periods are back to normal, I'm not on pill or anything...having regular sex...my body is completely ready to conceive..is there anything more I can be doing??? TIA xxx
