I'm 35 years old and had a miscarriage august, what can i do or take to increase chances of getting pregnant again?

I'm so sorry about your miscarriage. For some time, it's better not to think of getting pregnant again and to take care of yourself and your partner. Get your best healthy diet, do activities together, avoid alcohol and consider not trying to have a baby for this first year. Not trying to have a baby can be quite beneficial. Thus, avoid alcohol.
