Longing question. Some tmi. Please help :/

My husband and I just started our journey to a blessing in October. Being a scientific person I've done research and know the probability of me being pregnant in the first month is pretty slim to none. So this month was for fun. We had sex the week before ovulation, where he only finished like once and the day before my predicted ovulation where he said he only came a little, whatever that means. I started getting crazy sore nipples, crazy hunger, insomnia and bizarre dreams. My period was pushed back 4 times on glow. Finally I started spotting. Light pink and brown not even enough to fill a tampon. The next day it started brown, then purple, then was red with egg whites mix in. It was very light for me considering I have von willebran s and I'm usually bleeding to death off birth control. The next day the same thing. I started spotting then it turned red. Both days I think I used a liner and maybe changed to a pad. Neither full. The I spotted brown and now it's only when I whipe. My cervix also never dropped and got somewhat harder and has been closed. I usually have cramps so bad I can't stand straight. I am also getting rings around my nipples and my vagina is like purple. I took a test yesterday, negative ofcourse. I am just so confuse and keep getting information that's so conflicting. Like implantation bleeding can't or shouldn't be bright red. Then I read something about people bleeding the whole time they are pregnant. I just don't get what is going on with me if I'm not pregnant. Especially with my bleeding disorder, this was not a normal period even when I was on bc. Anyone have any suggestions or similar storries?? I feel like I'm going crazy because I feel pregnant, but all signs point to no. :/
