To TTC or to not TTC?

Hi ladies

I'm just venting basically. I've had two miscarriages this year. They were back-to-back, no period inbetween. It's the hardest thing I've ever had to deal with, but here I am surviving. 

I just finished my period last week, and here I am in my fertile window. My SO and I were talking about whether or not we should use protection. I'm so on the fence about it. On one end I would like to wait until the timing is a little better,  but at the same time I'm worried if I wait something will happen and I won't be able to get pregnant. 

***update

Turns out when I posted this I was ovulating and here I am, 10 weeks pregnant! I had a scan at 8 weeks and found a happy baby. I'm super sick all the time and it's been rough but I'm trying to remember that this is a blessing!
