Need Some Advice and Positivity

Okay so I have been TTC for over two years. I’ve had the mirena IUD back in early 2015 and it came out about two years later in 2017. My periods have been crazy since then; one month it’ll last a week, next month only four days, next month maybe a week and a half and so on. For the past two years almost three I’ve been trying TTC and haven’t had any luck back in 2018 I had a BFP and maybe two later after taking the test I started bleeding heavy. I went to the ER and was told it was none thing and that kilt me on the inside still does and it’s 2020 well the same thing happened again about a week or two ago. My period was about a week late that NEVER happens I be so scared to test because of what happened last time. So I just waited it out and out of no where what seemed like my period came but it wasn’t like my normal period. Bleeding was super heavy and everything about it was off. I’m back to square one again on the drawing board anyone had this experience or have any advice you could give me. I’m back with my sons father who is also the love of my life and I promise you we’re are definitely soul mates. And others think the exact same thing. I’m ready for more kids and so is he I want twins a girl and a boy however he’s only up for having boys.😤🙄🙄. If you have any advice that’s be great here’s a picture of my calendar to help. I
