Working out on the pill?

Have any of you ladies had trouble working out after going on the pill? I have to go on the pill for brief periods of time (usually about a month) for fertility cycles. I know the pill makes me tired and cranky so that is expected. What is not expected is being sooooo tired while working out. A couple of months ago I really stepped up my workout and added strength training and have been loooooving the results. But just a couple of days ago I've been so tired and winded I can't make it through the full hour. Yesterday though I pushed myself super hard to make it to 50 minutes and I felt like I had the flu for the rest of the day. Usually I feel great after working out.   So I don't know if this is just the pill (started a couple of weeks ago) or something else. Any ladies have some insight?

I haven't had that problem. Maybe you could ask for a different kind. I have been on Ortho Novum 7 for years

When I'm on the pill I cant work out because it makes me very tired and gives me a killer headache   I've tried different kind and such, but nothing has worked to correct it besides not taking it.

I'm really hoping it IS the pill because I can get off of it in three weeks!
