Hello, my last period was last month on April 25th. I haven't had sex in 6 months and then I did on may 10th, 11th and 12th. Only on those three days. I was expecting my period on may 25th but on may 19th and 20th I had brown spotting. Then on the 21st and 22nd it turned bright red mixed with brown. Only lasted those two days. It is now the 27th and I've experience semi-sore breasts but mostly on the side of my breast, the bumps on my areolas have enlarged, I always feel the urge to throw up but nothing comes up, tingling in my breast but it could be from becoming so cold. I've been very cold and it's the end of may, I've been very gasy and constipated. The smell is so horrible unlike usually and last but not least, I feel mild cramp like feelings but its directly in my left groin. It doesn't hurt, I just know it's there and its annoying. Could I possibly be pregnant? All my tests have come up negative. I also have shock like lightening pains in my vagina that go straight to my rectum.
