Best friend wants to go tanning...

She wants to go tanning and I can't go even though I love a nice tan. She doesn't know I'm pregnant and I'm not telling her till well later on once I know im in the clear for everything. Felt bad I'm sitting in the lobby just waiting for her , had to use the excuse I haven't been feeling good last couple days so didn't want to go into the bed and possibly pass out for the heat.
