TTC!!

I was put on the depo shot at 17. I got off at 18. I have been off for almost 2 years now and me and my husband have been trying for a baby. But No luck I've tried vitamins, different positions, eating healthier, exercising, etc. And still nothing but a bunch of Negative pregnancy test. My periods are irregular. I just started using this app this month tracking everything. I had a period this month and it says I'm ovulating now on the app. But on test they are negative... we have been trying for a baby for almost a year now and No luck.... 💔💔 Can anyone help me with advice or things I should try.... I have not been to an OBGYN because I don't have health insurance to cover it also afraid of what they may tell me. We want one so bad we can't stand it and every time I take a test and it comes out negative it just makes me want to give up..... 💔💔
