How soon is too soon ttc again?

Kr

Hi all, so I found out we were pregnant on 1/26 had very faint lines and was 11dpo, last Friday 2/1 finally got a positive digital test that afternoon started cramping and called my doc they said go to urgent care, went there and was sent to ER. Blood work and urine tests were done and ultrasound, ER doc said I was having a miscarriage/chemical pregnancy. I didn’t start bleeding til the next day which was very heavy. I was 4weeks and 4 days. I just had a miscarriage in November 7weeks 6 days. For some reason the most recent loss hit me harder then the the one in November. My hubs doesn’t understand although he has been very good through all of this. I can’t stop crying and I wonder when we should start trying again.
