I have had one as well in August and now I'm 7 weeks I just pray and hope everything is okay everyday. I keep my mind clear of negativity and make sure to stay humble everyday . I'm sure you will be okay but a Doppler is a great idea I think I'm going to get one as well daddy loves seeing his little blueberry baby and he would love to hear a heart beat everyday :)
I'm almost 31 weeks and I still worryvafter my miscarriage. It was devastating. It does get easier once you can feel baby moving tho
You could buy a fetal doppler about $60 then u can listen to the heart beat as often as you want to put your mind at ease.
I've never had a miscarriage, sorry for yours :( but I freaked until my 20week appt (anatomy scan) when I was reassured everything was perfect with my baby girl. Now that I can feel her moving all day I'm not as worried. Plus I think you kind of gain a intuition and can kind of sense what your babies upto. II'm 25weeks tomorrow, but still have my normal worries and fears some days :) congrats and good luck to you
