I haven't had any contractions that I know of. Or any Braxton-Hicks. I feel like such an oddball when I read all the 3rd tri posts about getting them early on, or for weeks on ends, etc. when I haven't felt a thing!
And the heartburn... yeah. I've had bouts of constant heartburn pretty much since 7 weeks or so. I'll go a few weeks or days battling it, then a few weeks or days of relief. Wash, rinse, repeat. I do hope I get some relief soon though and this spell doesn't last until the baby is born!
