TTC without luck 😢

Does anybody else have such a hard time when you see other girls post about their “unexpected” pregnancies and you have been TTC and doing literally all that you can do (opk’s, fifteen minutes legs in the air after the baby dance, eating a healthy diet, prenatal, etc) but you still don’t get a BFP? I want to be happy for them but at the same time it’s so hard cause my husband and I want a baby so so bad. I feel so disappointed in myself cause I feel like I’m so selfish because I’m jealous over them but it’s so hard to accept sometimes. Ahh. Just needed to get this out. Anybody out there with me? 😫
