Against the odds

Sa

I’m 39 years old and ttc... I’m still breastfeeding my 1 year old which I feel may be a factor working against me in this case. I took a test at 10 and 13 dpo with negative results.. I’m now 15 dpo and af was due yesterday but hasn’t come yet and I’m slightly afraid to take a test. Anyone have trouble ttc while breastfeeding? Af only Came back 4 months ago so I’m a bit irregular. Thought for sure I was pregnant this month but having cramps like af is coming for past few days
