Helpppppp please

So I had light spotting when I whipped 2 days ago and a little yesterday morning. It was literally a drops pink in color with my discharge. But I’ve had nothing since my boobs have been hurting for a week or so. I’ve had headaches, lower back pain/stiffness. And I’m completely drained and a little nauseous (I haven’t thrown up or even came close to throwing up)(I love chicken it’s my favorite food, but I’ve tried to eat it a couple of time and I’ve gaged. I’m discussed my the thought of it) has anyone ever had this. I don’t track my ovulation or keep my temperature but my husband has told me every night baby your burning up. He doesn’t know I’m going through this. We aren’t trying but we have sex 5 times a week at least. Or we were I just really haven’t been in the mood like I use to I’m just so tired I’m not on birth control, and we don’t use protection. Help

(Also I’ve had a little cramps not bad or even strong like twinges in the center of my uterus I feel like it started on the left side and has slowly made its way toward the center is that weird)
