Okay.. I got my period around the 21st of February, & got the bar on the 28th of February with little to no bleeding ( I had only just had my son back on January 3rd) I then had sex on the 7th of march (I was told to wait a few days before sex so I waited a week) My partner cum inside me and half pulled out (I was told I should be fine & also explained the risk) now my period is a few days late & im panicking... is this likely to be a pregnancy?
