Has anyone else been through this?

La

I stopped breastfeeding my daughter in August 2020 after feeding her for 13 months & ever since i have only had 3 periods. I last got one on 22nd July 2021 & i’m still waiting for the next one which is now 11 days late! I have had 2 blood tests, a smear test, 2 pelvic ultrasounds & everything has come back completely normal. I am currently under the gynecologist & when my next period decides to come i have been given a form to get another blood test done! He said not to worry but it is very frustrating when we want to start trying for another baby! Has anyone else been through or going through this please? Any advice would be great. Thank you X.
