cramping on my left side of my abdomen

Hello i am 28 years old and i been trying to get pregnant for the pass two years and finally i found out i was pregnant but in jan 25-14 i had a normal miscarriage then 3 months pass i have my period normal but in the 4&5 month they stop for the pass 2 days i been feeling tired lower back aching alot yesterday i star it smelling everything strong and throwing up all day to i just like blah i have cramping but No period on my left side my lower back is killing me i just wanna be a sleep last month took a pregnancy test and it was (-) this month am taking it tomorrow

I'm on the contraceptive injection, but the left side of my belly hurts after the intercourse. I had sex yesterday and today the left side of my belly is cramping on and off. What does that mean?

I just want to know if anyone else is having any problems like this? It starts out with my belly cramping on the right side then I have pain in my right leg. Very odd.

Help, I have quite irregular periods but this time I have abdomen swelling on the left side, pain in the middle of the abdomen and a late period. I have never had sexual intercourse. Any idea?
