My period was August 14-18. I had sex on the 23 and he did ejaculate inside me. when I checked the app the 24 was the start of my ovulation. A couple days after I began to have what looks like brown discharge/ blood but only when I would go pee and wipe I see it and only one or two times I’ve noticed the spotting in my underwear. My cycle is suppose to come the 12 of this month.
