Wonky Cycle!

In Dec I just ended an abnormal 74 day cycle with a really light, barely there AF and a bunch of days of spotting after. Yesterday AF showed up again making Dec's cycle a total of a whopping 13 days. And AF is back to normal and a little heavy.  Making a dr apt on Monday. I just got health insurance after not having any for over 3 yrs. So I am meeting a new Dr who I don't even know if I will want to keep as my primary AND I have to ask about all this. Praying to stay calm and trust God. I've been emotional and stressing. And I really want a BFP soon as possible! Especially since I'm already 32 tomorrow and we're only trying for our 1st. Extra prayers appreciated. Thank you in advance.
