I have pcos so very irregular periods. Havnt had one for about 5 months. I ended up taking a pregnancy test last month and it was positive. I went for a scan on 27th April and they said there was something there but it was too small to tell so booked me in for another the next week which was 4th may. At this scan there was a flickering heartbeat. She didn't say how far along it was. Just to book an appointment with a midwife. Does anyone know how far this is? And when I would have likely to have got pregnant?
