Cryptic pregnancies: what are they 🤔? A cryptic pregnancy occurs when a woman does not know she is pregnant until very late in the pregnancy, or until she is in labor. Talk about a surprise! It's possible for a woman to test negative on pregnancy tests, get their period, and not show a bump, all while carrying a perfectly healthy child. Have you heard any crazy cryptic pregnancy stories 🤰? We'd love to hear about them in the comments! - #crypticpregnancy #pregnancy #momlife #pregnantlife #pregnancyproblems.
