Is it just me?

Hi guys, sorry for the long post... i am just wondering if anyone else is still worried about miscarriage or if i am just being crazy? I have experienced 2 losses.. one in a previous relationship 10 years ago and one this past January with my husband. my first loss happened around 6-7 weeks and the most recent happened at 8.5. i am currently 15+5 and i am so hesitant to get excited or start buying stuff cause I’m terrified to lose our little boy. I know nothing is a guarantee of course but I’m just wondering if anyone else is feeling like that or if anyone wants to give any positive words of encouragement that would be so appreciated. We had our NT scan at 12+6 and baby was measuring a whole week ahead and was moving around in there like crazy. And all of our genetic screening came back as very low risk for chromosomal abnormalities. I have a doppler and have been listening to his heartbeat once a day (just for a few seconds i stop as soon as i find it) because it gives me peace of mind but i would really like to relax enough to stop using the doppler. (Also my midwife knows i have one and encouraged me to use it to help decrease my anxiety.. she said it is perfectly safe)
