I am 6 weeks pregnant and have had a horrible headache for almost a week straight. I've had 2 successful pregnancies and 3 first trimester miscarriages and the only other time this has happened to me was during one of those miscarriages. Right before that miscarriage, I had woke up one day to find the persistent headache gone and then I started bleeding later that day. I never had anything like that happen with my two successful pregnancies. I have an ultrasound on Monday (at 7 weeks) so I should have a better idea what is going on then but I'm just curious if anyone else was ever tipped off about a loss by a persistent headache (maybe due to dropping hormone levels?). I know that headaches can happen during early pregnancy but this one seems to be much more intense and persistent than I've experienced in the past.
