My name is charley I'm 28years old and nervous as heck. I noticed on my period tracker I was 12 days late but I thought that was normal because I had taken a plan B and those cause expected late dates within periods. I don't have a Regular period because with no insurance I haven't gotten on birth control and have been taking a plan b almost monthly. My sister convinced me to take a pregnancy test after i told her i was 12 days late and boom, just like that I was pregnant. Only to find out that I might have a sac with no baby inside. I'm stressed because I've never experienced anything like this I have a 7 yr old son his development and delivery went just fine. They say I should be 9weeks but they're going off my last period of may 1st and I don't believe My periods are even regular. If I did my math correctly I should be about 8 weeks, but I'm not sure. Has this happened to anyone and eventually the yolk sac appeared?
