feeling concerned about our fertility 😔

Megan 💕
So today my sister announced to the family she's pregnant... with twins, don't get me wrong I'm happy for her.. but heartbreaking for us that it seems everyone getting pregnant around us and it's taking so long for me and my fiancé to even get a bfp, we have been trying to get pregnant for around three years now and still nothing! I've tried vitamins, taking doctors advice with folic acid healthy diet, I don't smoke or drink, my fiancé don't smoke only has a drink on a occasion but not to much, we have even tried tips of google, conceive plus lube, and even trying not to think about it to maybe see if it happens without expecting... just seems nothing happening... any tips that can help? Would mean a lot to me! ❤️
