6 MONTHS SINCE MISCARRIAGE - TRYING TO CONCEIVE

[qz123]

Hello, I am 26 year old and got pregnant for the first time last year around august and miscarried in October therefore, almost 2 months. After that, my periods my have been irregular and so my period cycle. I have also gained weight that is triggering my PCOS. I have been trying to get pregnant for about 6 months but it is just not happening. My periods are definitely not in the cycle and I get headaches quite often. My doctor has advised me to get blood tests done. I am just really worried that how can I get pregnant so easily before and not now. I am really tensed that it could delay for years due to my hormonal imbalance or is this normal and I will get pregnant hopefully? Just need some reassurance and advise. Thank you so much for your time.
