Welcome! How can I help with your medical question? Hi, I had sex with my husband on the 6th of March, 3 days later thus on the 9th I had a very short and light bleeding for 3 days. (my period was due on the 15th of march buh didn't show up). After this short and light bleeding, i have been experiencing severe sore breasts and slight on and off cramps for over 2 weeks now. Moreover I feel very cold mostly and have increased body temperature mostly at night. Could I be pregnant? Have you seen a doctor about this yet? What medications are you taking? I have not seen a doctor yet and not taken any medication too Anything else in your medical history you think the doctor should know? No please
