Trying to conceive after 13yrs

My husband and I are trying to conceive after 13 yrs. I had Mirena IUD for 8 yrs and final had a my first period last week. My ovulation dates start today. I have mixed emotions scared and excited. I had a pregnancy test done last month (after 2 months removing IUD and no periods) and it came out negative. I think its because my body had to get adjusted to no IUD in place. I am just hoping this month is different.
