Pregnancy after miscarriage .. long post

So I found out that I am pregnant today. I am so excited but after 6 months of trying and 2 back to back miscarriages in March and April I can’t help but wait for the other shoe to drop. I am trying my best to stay positive but it’s so hard when I had my heart broken twice in a row.. I guess I’m just asking for advice on how to not get anxious about the weeks to come. I am 15 dpo today, 1 day late and found out this morning. With the losses I didn’t find out until it was the faintest of faint lines about a week after I missed my period.. So maybe that’s a glimmer of hope? I have no clue, but I’m scared and excited 😬
