My husband & I have been trying for several years to conceive. We had 2 miscarriages one in 2019 & Feb of this year was our last one. TTC was taking its toll on me mentally & I stop the daily tracking. So I did take OPK on CD9 & it was positive, but pregnancy was negative & randomly tested a few days later & OPK was negative. So I assumed I had ovulated then, but today I took another OPK & it was very positive. But its only CD 18 per Premom app & <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a>. My boobs are sore, headaches, no energy & I stay with a back ache. Can you ovulate twice in a cycle? Top 3 are CD9 & bottom 2 are from today CD18.
