Chanel🎀 • 20 years old🎉 expecting baby #1 due july 11th 🚼 engaged 💍👰🏾
So I'm going crazy. Last time I got my period was March 20th-24th yesterday went to a pregnantcy testing clinic they told me I was not pregnant. It odd because I get my period two times a month. I'm not sure what's going on I have no Insurance to go to a obgyn what should I do ? Is it possible that's the clinics test was wrong and I'm just really early?
