Hey can anyone help? On the 18th off nov I had a chemical pregnancy and was bleeding for 6 days, as soon as the bleeding stopped I had unprotected sex on the 23rd and 24th and didn't think it would be possible to fall pregnant at that time but getting every pregnancy sign back as before!!! Sore chest, swollen and funny feeling tummy (a little unlike my pms) sore back...is it possible to be pregnant again?
