Ok so me and my boyfriend have been having unprotected sex. This month my period was late. It always comes on the 15th of every month. I been feeling sick, bloated, always hungry, sleepy, boobs are so sensitive, lower back pain, and lower stomach pain. Then on the 23rd i got very LIGHT pinkish spotting when i wiped. 2 days later when i use the bathroom i had a heavy blood flow when i wiped but now its back to light pinkish spotting every here and there. Could this be my period or can i be pregnant??
