I’m 13 days late on my period, if I was somehow pregnant I’d be about 10 weeks but I don’t feel this is very likely as I did have a bit of a period at the end of April however it could have potentially been implantation bleeding for all I know. I feel like surely if I was 10 weeks pregnant it would have showed up on a test by now? I’ve never been this late before so I’m a bit concerned and have booked an appointment at the doctors. Is it possible I’m pregnant or what do you think could be causing this?
