Please help

So, I have been ttc for a while now. I have a regular period of 28 day and I think I am suppose to ovulate on the 14th day of my cycle. over a year now, I stopped seeing cervical mucus. Most times I am not opportune to meet with my hubby on the 14th day of my cycle but we definitely do on the 12th, 13th and 15th in such case. Recently, my gyn asked I go for a hsg test which I did on the 5th of this month. Today, my period is 3days late and I am not pregnant. Pls I need candid advise and suggestions. M getting so desperate 😢
