I would consider the Clomid also. While Clomid is very well tolerated in the vast majority of people, at least at low doses--and 50mg. 3x week is a low weekly dose--the 50mg. dose MAY, in your case, be enough in a single dose to induce blood pressure spikes. I believe it is the cause of blood pressure spikes in myself when I use it at 50mg./day and above. If you were to look on online forums of Clomid users, you would be able to fairly easily finds threads related to this very question--can Clomid cause an increase or spikes in blood pressure.
You might want to consider switching to 25mg./day dosing. It's just a slight increase in the total weekly dose, and has been found to be safe, efficacious, and well tolerated in clinical trails.
