Miscarried :(

Mrs. • 😘
After my 30th birthday, my husband and I started trying for a baby. I haven't been on birth control since we got married but we were using condoms or the withdrawal method. We've been doing this for 6 years and never got pregnant so it worked for us. We conceived 12/5. The week after Christmas I started spotting. OBGYN did a vaginal exam and said everything looked ok but that I needed to return for lab work to see if my hormone count was increasing (still pregnant) or decreasing (likely miscarriage). The spotting increased significantly and turned into more of a period. Cramping was horrible. Clots were large and frequent. My doctor told me to go to the ER right away (I was out of town and couldn't get to her office sooner). Went to the ER. They took blood work and did a vaginal exam. My OBGYN sent the ER my lab work to compare the hormone levels. It had dropped by over 50%. My husband and I were crushed. It's been about a month. My first period post-miscarriage came 3 days ago. We want a baby but we dint want to experience another miscarriage. We're both large people. I've lost over 86lbs, however, to help ensure that I can carry a baby to term. I'm not site if that's enough, though. Any advice for starting over and improving my chances for a successful pregnancy?
