Been feeling weird for days but still negative :( Progesterone or early pregnancy?

So my boyfriend and I had sex all throughout my fertile window. He came in me 5 times in 3 days during my window including what I suspect was my ovulation day. I’ve been feeling symptoms non stop since ovulation. But I’ve been writing down everything since 5DPO. I usually never feel ovulation or any PMS symptoms this early in my luteal cycle. The fact that I was able to feel ovulation this cycle is just making me believe that maybe I’m having a stronger hormonal cycle but I’d like to get others opinions. My symptoms have included: mood swings, nausea, bloating, cramping that’s getting worse day by day, gassy, and soft stools, 6DPO I wiped and saw pink on my tissue, sensitive stomach, frequent peeing but that’s mostly subsided, burpy, feeling of needing to push and nothing coming out, feeling like my period is about to start for days… I could go on. I’ve never felt this way before a period and I’ve been testing for three days now since 7DPO and it’s been negative every time. Do y’all think this is just a strong cycle or could I be in early pregnancy?
