Hi,
If there is a history of
unprotected intercourse around the time of ovulation, there possibility of
pregnancy. Few days delay in menstrual periods and fluctuations in the amount of menstrual flow can be seen frequently depending on many causes. Abdominal cramps, headache, breast tenderness, etc. symptoms can be seen during pre menstrual period also. So, just by symptoms we cannot come to an conclusion regarding the pregnancy.
According to your description the sporting you mentioned may not be menstrual period unless it turns into a regular menstrual flow. It could be postcoital spotting due to minor breaches on vaginal epithelium. If you want to be sure and if you do not get your menstrual periods, even after one week of your expected periods, please go for a urine or
blood test for pregnancy. In blood test for pregnancy if
serum beta HCG levels are less than 5 mIU/mL, it rules out the possibility of pregnancy, levels above 5 mIU/mL indicates the possibility of pregnancy.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Sree Gouri S. R., OBGYN
