I don't know about #1, but #2 happens to me, I'm right at 30 weeks. Its uncomfortable, kind of painful, but its happened to me every so often all through this pg. Some days are like that, 3-6 times, then I won't for like 3-4 days. I just try not to strain too much, and eat plenty of fibre and fruit, I don't know if there's much more to be done for it.
