cryptic or stealth pregnancy!?

Hope
Hello all. 
I'm 33. I have two teenagers so this isn't my first time at the rodeo. 
Let me give you my whole story. 
My period typically comes on day 32-33. This is only this past year.  September I had a 54 day cycle and it's jumped all over the place since. I have gained 20 lbs since Oct 17th. 
I had bronchitis and I was on antibiotics and steroids for three weeks. Then a week after going off I ended up with the worlds worst Yeast infection ever. I don't typically get them. I was treated with two rounds of Diflucan and it didn't work. Then they gave me a 7 day injectable. vaginal cream. That finally helped. 12 day yeast infection was hell. Now at cycle day 22 I had spotting. Then today cycle day 23 I had my "period" but it was very light. So it would be 9 days early and light. 
Today and tonight my stomach keeps feeling like I have a baby moving inside me. That's a distinct feeling I've never had while not pregnant. So I look it up and what comes up? cryptic or stealth pregnancies 
Anyone have any insight!?
