Can not consume

Ok so I have been with my bf for over 2 years.. we have trued consuming for over 8 months and Nuthing happens. I have a 3 year old son who is my world but I want to have more to keep him company, but for some reason it’s been hard to conceive. 😞 I feel like I am on the point of giving up because of the fact that it is painful. To try and not be able to get pregnant.. I don’t know what to do at this point.. I feel sad.
