Pcos and pregnancy.

Just found out I'm pregnant with my 3rd and I found out I had pcos after my 2nd baby girl, had problems with period since and they've been on and off but only started getting them back on time recently so me and my now oh started trying since January and finally pregnant☺️ roughly 6 weeks 1 day today, got midwife Tuesday. And I'm just so so worried there's something wrong with baby or no heartbeat or something like, as Drs can't tell me how long I've had pcos I'm not sure weather I had them with my 2nd baby or not. So over worrying a lot now😩☹️

Also had a few cramps, achyness at bottom of tummy and in tummy, pure backache and just feeling generally bleh from day to day but no sickness just as yet💁☺️👶🏼

Any advice to stop worrying ect? Or any one else been in his situation.. thanks in advance girls!
