3years ttc

I have a pretty hectic life. I stay stressed and have NO time or energy to improve it. I have a 4 year old in school with Autism. A husband. A crazy family. Limited income. Ive tried for three years to get pregnant. No luck. Had tests done... Nothing is wrong.They say its either HIM my weight or stress. Ok..idk if its him. I was this big the last time i concieved and then the stress...my mother in law last night gave me a low mg valume she is perscribed to help me sleep. When i woke up. On cycle day 53..i finally started my period. Is that what i need to regulate my period
