I need help with an excuse as to why I can't go in a hot tub (but could go in a pool or lake...). I'll be 7 wks and have read enough about neural tube defects I don't want to risk it. But we're traveling to see family and they know I loooove a good hot tub soak. I've miscarried before so we're not telling anyone in the first tri and I haven't even had an ultrasound yet so really don't want to spill the beans. Help!!
