Positive ovulation tests for 3 weeks

Kaytlyn • 25 and trying to get pregnant for the 5th time! lost baby #1 due to a miscarriage when I was 16. I had baby #2 when I was 19 and I had baby #3 when I was 21. I had baby 4 when I was 23. One happy mommy :)

I have been taking ovulation tests since shortly after I ended my period. For about three weeks now they have all been positive. I've tried different brands to see if that was causing it but it's still positive. Pregnancy tests have all been negitive. Did this happen to anybody else? I could really use some advice, it's worrying me.
