Hello, and thank you for your question. I will be happy to assist you. Answers are for educational purposes only.
I am sorry you are experiencing this.
Unfortunately, it is very common to have an irregular cycle once you start monitoring them. I see it all the time and it is likely due to stress.
The ovulation kits unfortunately are not 100% accurate and can give you misleading information like you have experienced.
If you have been trying to conceive for 18 months, then you really are past the point of trying to do home monitoring by yourself.
You really need to be seen by a fertility specialist so that both of you can be tested. Your husband needs a semen analysis. And you should have blood work done and your cycle monitored in real time with blood work and ultrasound.
Also, you may need a radiology test to look at the fallopian tubes to see if they are open.
Ideally you should be trying to conceive every other day throughout the whole month. Based on 27 days cycles, your peak fertility time is Day # ***** to 16 (if you count the first day of your period as day # *****).
But I would not get too concerned about the abnormal cycle this month. If your pregnancy test was negative at 10 days late, then you did not get pregnant this last cycle.
I really hope that you can arrange to see a fertility specialist. At 18 months, that is what is needed. The ovulation kit is going to be of limited help at this point.
I hope this is helpful.
