I have a 31-32 day cylce. monday was day 31, tuesday was day 32. I still have not received my period and it is day 35. Back in april, before i was sexually active, my period came on day 35/36, but now that i am sexually active, i am a bit worried. i had lower stomach pinching pain on one side monday-yesterday morning, but now it has stopped. last week, my boobs were sore, but this week the soreness went away which is usually when i would expect my period. I have no naseau, pain, headaches, sore boobs, or any of the other early pregnancy signs, is pregnancy likely?
