Positive LH test for 1 week

Allie

Hello! I’ve been testing with LH strips for 4 years now. I’ve had 2 successful pregnancies and now trying to avoid pregnancy. So I’m very familiar with my body and testing. This month I’ve started with VERY positive test strips for going on a week now. I’ve never had that happen. Usually I’ll get a build up then my peak and it will then start to go lighter. I’ve taken a HCG test and it’s very negative. Has anyone had this happen. Should I call my OBGYN?
