Just A Quick Question

So yesterday I was sitting in my room watching tv and felt something wet gush out thinking it’s Af I ran to the bathroom and this is what I saw. Now my fertile window is over and has been for a few days and I didn’t BD during. What I want to know is I had a period earlier this month but it was quite short (4) days and I go (6/7) normally. Could that have been I.B ? like could I have conceived and still have bleeding. I don’t really have any symptoms besides a dull ache that goes from right to left . My stomach does feel slightly firm when I press on it (right above my pelvic bone) have any of you ladies had bleeding then got a bfp ?
