Came inside, she's on bcp

Problem/Goal: Hello, last day ng ovulation ng gf ko kahapon according sa calendar nya and i came inside her kagabi.

She's on bcp naman and next week pa matatapos yung tinatake nya na pills ngayon. Ik bcp ay effective naman and all and tapos na nya yung 7 day window ng pills since mag s start na sya mag take ng placebo pills nya next week so nasa pang 3rd week na sya. Medyo nakaka kaba lang kasi last day ng ovulation nya kahapon and nag cum ako inside her kagabi. Ik that's pretty stupid so save the judgements.

Pretty stupid question to ask but are we protected?
