Overthinking?

Yesterday during our BD I had this sharp pain in my left ovary (never had that happen). It’s been two years since my last pregnancy so it’s hard to remember what specific symptoms I had in the first trimester. Also I’m 4 days late, AF nowhere in sight 🙏🏽 Gave up trying after the first two BFN’s these past couple months, didn’t want to get so down on myself for not getting pregnant as fast as I did with my first baby. Hoping I get a BFP soon, is it too early to test? Any wisdom is appreciated! ✨
