OPINION PLEASE ???

We Absolutely No Problem Conceiving We Have 4 Children And We Were Going To Try For Our 5th And Final Baby Next Month But Since 3 Of Our Children Are very Close in age I Started Tracking My Cycle And Taking Ovulation Tests And Basal Body Temperature To Prevent Pregnancy for a while and to get to know my body and I also use this app and a <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a>. Well I Got A Clear Positive Ovulation Test On June 15th And I Had The Ovulation pain As Well but Today I Was Having Some C r camping And I Took Another And It Was Clear Positive Again So I Googled it And Got A Resault Tgfat Said Ovulation Tests Can't Tell The Difference Between The LH Surge And Hcg and Hcg can give A Positive Reading on An Ovulation Test But We Was Intimate June 10th And I Ovulated June 15th that's a 5 day gap so why would I be getting positive ovulation tests still and both lines are equally dark.
