Can I vent to you all

I feel a little drained, so I experienced loss three times, the last one being at 15 weeks. Ever since my last loss my periods are extremely irregular which is making it harder to ttc for me. This month I was a week late and then AF shows up. I don’t know why it was easy to conceive my first but it’s been a very challenging two years ttc for my second. Any advice or any of you can share personal experiences to see what can I do.
