Migraines after sex and during pregnancy

I’m 34 and have been suffering from migraines with aura since I was a child. Most often I get vision changes and vision loss as well as numbness that can start on one side of the body and travel to the other side, and when it’s particularly bad I also suffer memory loss and inability to speak etc. prior to the headache and nausea. I have tried medication but nothing has worked. I usually get migraines about once a month.

I was wondering how many of you are also suffering from migraines after sex, and if you have found any ways to avoid them. To me it happens every now and again, the more intense the sex the more likely it is I’ll get a migraine after.

My husband and I are trying to get pregnant and I recently experienced a chemical pregnancy (very early miscarriage), during the weeks after conception I had about 3 migraines a week and after that I’ve been having migraines after sex a lot more often than before. I’m suspecting it’s all due to the hormones but would appreciate hearing if others have had similar experiences and if you have found anything to stop this from happening.
