Am I nearly positive ladies? OPK

Hi girls. Here is an opk from last night (top) and this afternoon (bottom). We plan to BD tonight. Am I likely to catch that egg? I will test again later tonight and tomorrow afternoon to make sure it's getting darker but i sometimes miss my peak. My clearblue digital OPK said low fertility this morning but a lot can change in a few hours am I right? 😊 I reeealy need some feedback xxx
