Opinions needed ladies 😔

My periods have been so irregular since my miscarriage back in September of 2015. I got on birth control to regulate and I got off of them October 2017. I had a period in October and my next one was was in February. The February period lasted 6 days. Then I had one in May that lasted about two weeks. After that I had my last one which I just got off of and it lasted about two weeks as well. Does this sound like it is trying to regulate on its own?

Backstory: my bestfriend of 12 years has 3 kids and is pregnant again (all kids have different dads.) We are both 22 and she asked me if I wanted to adopt the baby she is pregnant with now because she was in a very abusive relationship, which I agreed to do. I flew her back home with me and her family in Nebraska, gave her money to get back on her feet. Now she is telling me she wants to keep her baby. Which I’m ok with because it is her baby but I am hurt because I finished the baby girl nursery, picked a name, and was so excited I was getting another opportunity to be a mother and I feel robbed of it once again. So I’m hoping I can make my own dream come true and naturally conceive.
