I am currently going on 15 weeks and recently got back to the gym after a hiatus - one that lasted even prior to my pregnancy and throughout first trimester. In the past, I've done strength training and running. I certainly didn't want to overdo anything, so I started by walking on the treadmill on an incline - nothing big at all but for an hour at a time. I drink water the entire time and hardly even work up a sweat (I could have a conversation easily). After I'm done, I've noticed that a headache settles in for the remainder of the day. It feels like a sinus or tension headache. Has this happened to anyone else and if so, what was the outcome? I'm trying so hard not to overdo it but for some reason, even when I exert myself just a little I get a headache. This has been going on for over a week, now.
