Need help.. TTC with irregular period

[Amayara]

Hi All.. I am ttc.. I have monthly cycle length 34 average.. we r ttc for 4 months with no success.. I used clear blue advanced opk.. with clear blue I got my peak fertility 7 day before my next period is due.. is it possible that I got pregnant.. 13 sep was my due date of period.. but I got negative pregnancy test today. Can Any body tell own opinion on this

I feel your pain, I have irregular cycles so it is hard to predict.
So if your peak on CB was 7 days before 13th then you likely ovulated on 7th Sept which would make you 11dpo. It may be this cycle is a bit longer for some reason.
Most people won't get a positive until 12dpo so it is possible you are just testing too early.
Do you take your temperature? If not I recommend it for irregular cycles as you can see the temperature rise after ovulation and it helps to show you where you are in your cycle. Fertility friend is a great app for that and free.
I hope this helps! Fingers crossed for you.

Ya may be I am testing early.. so i’ll Wait for some more days..

Definitely test again in a few days/ a week and see if you get any signs. I had a few negative tests and ended up going to the doctors because of how i was feeling and they did a test which was positive. Also took some vitamins which i think were called 'trying for a baby' or something, not sure if they helped
