I have had a lot more headaches this pregnancy than I did with Andrew (I think I maybe had one or two with him). The past 2 weeks, I have probably had a headache 5 out of 7 days a week. I had the nurse at my work check my BP, and it was fine (105/69, which is normal for me). I have no clue, so I'll just say it's the hormones!
I used to get migraines ALL THE TIME, starting in 2nd grade. In college, I kept a headache log and realized that in a month, I was getting 20-25 headaches. I was finally diagnosed with migraines at age 19 or 20, and went through some prescription trials. What finally worked for me was Topamax daily (an anti-seizure medication) and then Imitrex 100mg on the onset of the migraine.
Then, when we got married in 2006 and started trying for a baby, I went off all medications, including the birth control pill. My headaches magically disappeared. Eight freaking years on the pill and I think that was the culprit (but it doesn't explain my childhood headaches, which I think were stress-related).
Anyway, these headaches I have now are very mild compared to the ones I used to have where I begged DH to just kill me (thanks for not listening, honey!).
On a positive note, I have been feeling more movement here and there. It's about 3 weeks earlier than I felt it with Andrew, so yay!
