I'm terrified 😭😭

Hey guys, I'm back after been off here for a month. Got pregnant back in January after having my first miscarriage back in May 2018. I lost my second baby on the 25th of March. My period returned on the 21st of April, was so painful to say the least. Currently 2dpo and the wait is killing me, I'm also very anxious and terrified incase I am pregnant and the outcome is the same as March. Has anyone any good advice as to how to try and overcome this feeling. Like I'm loosing sleep over the fear of losing another baby.
