Teeth & Gums semi-rant

Since beginning if last year I've really gone into getting my gums and teeth health back in control. But since becoming pregnant I feel like I can't keep up. I had a root canal and filling at end if first trimester. Had a cleaning two weeks ago and felt great. Now last few days my gums have been swelling and causing pain that keeps me up or gives me a headache. Ugh. Just can't get a break.
