Carina

Hi ladies my LMP was April 5th-10th recall slight bleeding after it ended so now quiet sure when it really did end. I usually ovulate pretty late also considering I was on the birth control patch All of March me and my boyfriend decided to try so I removed my patch. And actively tried April-May. On May 6 I took a test it was negative. May 13 i felt so sick that I took a test and it turned out Positive. Well the first ultrasound picture you see is May 21st there was basically nothing but the sac and yolk. This past Friday I went to the ER because I had a burning sensation took me to a ultrasound tec that was high resolution she should me the baby and it’s little heart beat I wanted to cry from joy 😭 well yesterday second picture I went in and there was nothing 😐😞 I recall the ultrasound tec zooming into my gestational sac to see baby she said it was measuring half an inch which is 2.5 millimeters I go back to the obgyn tomorrow for a HCG check and Monday for an ultrasound update. I have no bleeding or cramping idk what to think :(
