Late period, negative test, pink discharge

Hey y’all it’s been years since I posted on here, but I just need someone’s input. I’m 4 days late, I had major cramps on day 2 of being late thinking AF was coming & she didn’t, had sex last night & pink discharge right after (cervix was high, soft, & open), so I fully expected AF today, but nope. I had regular cm this am instead. Wtf is going on. My hpt’s are negative, I’m bloated & constipated, I’m never this late, I have endometriosis, but a very regular period for someone with endo. Could I be pregnant? With my son I found out at 10dpo, but I was on a 100mg clomid cycle that month. My husband & I don’t use protection at all because if it happens it happens, & endo is it’s own form of bc lol (dark humor from prior 3 years of TTC). What’s the latest y’all got a BFP? If I’m pregnant that’s cool. If I’m not that’s cool too. I just NEED to know so I can make some changes in my daily life.
