Suggest Treatment For Abdominal Cramps And Heavy Menstrual Period

Hi my names Candice,

About a week ago i started getting really sore boobs, the veins became more visible, nipples started getting bigger and i have just noticed i have stretch marks on my boobs. I thought i could be pregnant (ttc) but took a preg test and it came back negative. I was due for my period today, but it came yesterday. Yesterday when my period came i was fine until i had a milkshake and almost straight after i started getting really bad cramps, they were so painful never had cramps this bad, i took 2 pain killers because the pain was too much. Today i was still feeling light cramps and then i went to the bathroom and i had really big blood clots( this is not normal for me). Please help

Ps. My right boob is still sore.
