Any suggestions?

My doctor is literally no help with my infertility. I have been trying to do my own research to do things to hopefully keep my next pregnancy. I have a 3 year old boy I had effortlessly. we started trying again when he turned two. I suffered a blighted ovum the first time. A chemical two months later followed directly by a miscarriage at 5 weeks. I don’t know if that’s considered a chemical. My lines on my pregnancy test were so strong the control line was gone and my quants were good with the doctors but ultrasound showed at 5 weeks no sign of pregnancy. And I bled two weeks later. She took a million vials of blood a month ago and I’m yet to hear back. I asked her if she tested my progesterone because ever since my first miscarriage I spot two or three days before and after my period. No answer on that either. So I purchased natural progesterone cream. I stopped taking folic acid and purchased pholate. I take a baby aspirin per doctors orders. I take an extra vitamin d supplement. I stopped eating gluten and processed sugar. I don’t know what else to do on my end. I don’t know exactly how much and of what kind of vitamins to take. I don’t want to take too much but I know I’m deficient in a lot of them just because I have a history of being low on iron..etc. i guess I would

Just love your guys stories or what worked for you. I want to switch doctors but that’s just more months of waiting to be seen and I still might deal with the same issues I’m dealing with now. Sorry for such a long post.
