Hey mamas soon to be 😉! I need some advice!

I’m 21 years old and I’m trying to have a baby. We have been trying for over 6 months now and I haven’t gotten any positives so far unfortunately. I eat well, sleep well, take my vitamins, and don’t drink or smoke. I’m young and healthy, but I just can’t seem to get pregnant. I need some help and advice on what to do and change in my life so I can get pregnant. I want to hear all your secrets on how to make this happen successfully and quickly. Thanks girls 🙏🏽
