How long are your cycles normally? CD 15 is pretty high.. was it a peak at one point? It’s possible your body geared up to ovulate & failed and that’s why you peaked again CD 23
They’re usually 31 days. I think I’m not managing to ovulate
I think it looks fine. It’s normal for levels to fluctuate throughout your cycle. Some women have a steady rise, some have a quick rise to peak and then drops. Both are normal. Can you send a picture of your test window?
