Ovulation Testing

Hey Y’all! So this hasn’t been a very long journey for me so far but i was pregnant was i was much younger and didn’t carry the baby as my mom had other plans. this worries me that due to the termination i may have some internal damage and that may be causing fertility issues. i take ovulations tests once a day and even during my peak of peak times the line still isn’t darker than the control line….and kind words or things maybe me and my partner can do to see if it’s just our bad timing of testing or if there’s a need for us to get tested! Thank you for all the help in advanced :)
