Need some encouragement

So I previously joined this group in September 2018 because I was desperately trying to conceive after a loss

History:

I have had two miscarriages

1) was a second trimester miscarriage caused by a infection in my placenta, I was 17 weeks pregnant, caused my cervix to open and sack was to far down that there was nothing that could be done

2) was a first trimester miscarriage, I was about 5-6 weeks pregnant(and as you guys know theres never really answer they can give you when it happens that early on)

3) they were almost 7 months apart to the date lost the first baby May 29th and the second one December 27th 2018

So now I'm trying to get back up on the horse to try again but I've just been feeling really discouraged and questioning my self on what could I have done to have prevented my previous losses or what I can do differently when the time comes again. It's just like as bad as I want to be pregnant again my fear of another loss is greater but I dont not want to try again because I know every pregnancy is different. I find my self feeling like I'll never be able to enjoy being pregnant again because of my previous ones and is already worrying about the what if's.

Today's news:

This week is my ovulation week and just need some encouraging words to help me relax and try not to stress so bad about it

P.s thanks in advanced for reading my post and leaving your kind words.
