Hello, I found out today that I had a miscarriage. I assumed I was pregnant last month because I missed my period and just had that feeling. However, it was never detected in my blood. I had a blood preg test on Dec. 27th and took several at home tests throughout the month of Dec. All negative. I had tissue fall out of my vagina one week ago jan 21st and the dr suspcted pregnancy so they did another blood test but came out negative again. No hcg was ever detected in my blood. They sent the tissue off to pathology thinking it was something else but it was determined today that the tissue was part of the placenta and that I actually did miscarry. For 9 days now I have been suffering from a non-stop head pain on the left side of my head and at times it turns into an unbearable headache..migraine type..that lasts nearly all day, preventing me from doing my daily activitied because its so painful. I have also been woken up at night by an awful stabbing pain on both sides of my head, almost like an electric shock. Very painful. I have never been diagnosed with migraines. My dr has scheduled me for an MRI of the brain next week. Any ideas on what type of headache this might be and if it is related to the miscarriage?
