Opinions?

My period started 12/4 and ended 12/9. We BD on 12/9, 12/12/ 12/13, 12/16, 12/17, 12/19. I should have ovulated on 12/19. On 12/21 I had cramping in the morning and it went away. The same night my nipples were way bigger than normal and it happened again two days later. Yesterday I had a dream I took a test it was positive but someone stole all my tests before I could tell my fiancé and I woke up crying lol. I took a test and it was negative so I think it was too early. I had a dream last night that I was wiping myself down there and I had light brown/pink spotting aka implantation bleeding. Today I’m cramping a little but it’s not cramps I just feel tense. Also I’m either super constipated or I’m having diarrhea. I either get so much sleep or not enough sleep. And then the last two days I have been so congested and full of sniffles and full on headache. I had the sniffles accompanied with a metallic taste in my mouth yesterday. Today I have the sniffles again with cramping but not period cramping. I didn’t take a test this AM because I figured it would be negative. But I’m hoping it’s positive but I also want this month to end so I know if we’re trying next month or not. On top of that I’m usually 115lb and last three days I’ve been at a steady 120lb and I NEVER keep on weight and I’ve been having bowel movements or I’m super gassy.

Could these be symptoms or am I just crazy?
