Testing positive on an ovulation test doesnt mean you will get pregnant or, unfortunately, that you even ovulated.
There are many different possibilities for what may be going on.
1. You might be pregnant and it simply isnt registering on a test yet.
2. Since you have irregular cycles you may just have to wait a while longer for your period.
3. You may have PCOS (irregular periods are a symptom) in which case the ovulation tests don't really work for you since they may always appear as positive.
4. Even though the test came out positive you may have missed the ovulation by being too early or too late.
5. Your body may have been preparing itself to ovulate, thus the LH surge, but you never actually ovulated (this can happen multiple times over a cycle and one can have positive tests for extended periods of time) I know that I get positives even after I've ovulated when my LH is decreasing since it gets so high and I can go through cycles where I will have a couple of days of positive, a few negative, 3 or 4 more positive, more negative etc.
6. You may have been dehydrated when taking the ovulation test and it showed a higher LH level than normal.
7. Everything could have gone just fine but the sperm simply didn't fertilize the egg or the egg didnt implant. Perhaps there wasnt enough sperm or who knows what. It can be quite annoying.
There are more reasons as well but those are the most common. Just relax and you will eventually get your period or have a + HPT.
If you think this cycle is more abnormal than your typical irregular cycle, go see a doctor.
