Hello, im 19 years old and 6 days ago it was the last day of my period. The next day me and my boyfriend had oral sex. Since 3 days ago i have cramps like i am on my period and they will not go away. Also last week i started working out a lot (mostly situps and leg workout and i feel my muscules are sore). Moreover, i have not been eating as much as i usually do and i lost some weight because of stress...so could my pain be connected to the workouts and stress? or did something happen during oral sex (i mean could i be pregnant or is something else going on)??
