Ttc #2 no pills at this time but...

I’ve been trying to conceive since a year and we’re still trying. My period is always normal, you know red blood. But this month has my period last week and it was brownish blood for 3-4 days. Seem like is irregular. Anyone know if is normal?

Also want to consult cause all these months has negative test, is so frustrating and wonder why not positive 😂 I understand you all struggle. But wonder what OB do? 😂 any advices, don’t judge please everyone has the same situation.
