if someone could help me that would be fantastic!! so I thought I would be starting a normal period but was just getting pms super early. I was hungry all the time, but no cravings. I don't really want to eat even though I'm starving, it's weird. my boobs hurt pretty bad, I was moody and I'm still really emotional and idk why. but then 10 days early I got what I though was my period, it was really light at the beginning but with some bad cramps, I usually start out really heavy with unbearable cramps and everything just gets worse as I go on. but not with this. Then the cramps went away and it got a little heavier for only a day but it still wasn't bad. then it got lighter and now it's even lighter but I keep seeing clots. there's only been about 5 of them but my boobs stopped hurting. is this a period?? or implantation? I'm really hoping it's not a miscairage. it's not like a normal period so I have no idea what's going on!! I think it's too early to take a pregnancy test though so can someone relate or just help?? it's kind of scaring me
