Advice ..

I’m here to ask for some advice , because I’m at a point where I don’t know what to do or think anymore , I’ve always wanted to be a mom because of my experience with my mom was not a good one it’s always been a dream to be the best mom and not make the same mistakes as my mom , I’ve been in a relationship for almost two years and we’ve never used protection and it’s been about 5 months where we’ve actually been trying with following apps and having sex during ovulation and no luck , seeing one of my friends from school being pregnant and feeling her baby grow month after month made me want it more , I let it go for sometime but now finding out my best friend is pregnant I couldn’t be more happy for her but it made me feel sad both my friends got pregnant and I’m about to be 20 years old and I’m worried that something might be wrong 😔😞
