Trying again

well I dont know where to start. I am 35 I have had breast cancer twice. obviously I beat that green monster. I have PCOS. my husband and I tried getting pregnant before we got married in 2012 with no luck. I had a failed implantation once but nothing ever happened after. we topped out at fertility treatments we just accepted it. during a routine MRI I was told I couldnt bc I was pregnant! I cried guys so hard and it was 3 weeks before xmas in 2016 so I had to keep a secret from my hubby and mom. we were all so happy finally and it was our precious girl we dreamed of. but sadly at 24 weeks I got pre eclampsia and after 3 weeks in the hospital I was forced to have a csection. our baby lived only 2 days. I know this is a serious tear jerking story but I feel like I am ready to put the effort and mental space to try again. I mean I've never not trying but I think I'm ready to focus on it again. I just hope it doesnt take another 4 yrs to get pregnant. I had gotten back to if it happens it happens but I'm getting older and I'm getting scared of never being able to truly be a mother. I hope I can keep my emotions together. please say a prayer for me guys. thank you.
