Hello, I have been having more pain during this period that other times before. My breasts are very swollen and when I squeeze them, milk comes out. I took a pregnancy test and it came out negative. I felt very fatigued 2 weeks before my period came, I was having cravings. Yesterday when I got my period it started pink, then it went dark and then a long jelly like blood clot came out and it s been heavy ever since and I have a lot of lower abdominal pain, also my left sciatic nerve is causing pain on my butt cheek. What do you think is going on?
