Testing on March 22nd??

Becky • Busy SAHM with toddler and newborn!
I've been dealing with some odd occurrences the past 2 weeks. On 6 DPO, I had a crazy crying attack at work and had to leave....for no reason! I've been having heartburn after drinking water, and I rarely suffer from heartburn. 
​On 10 DPO, I mouthed off to 2 Walmart employees over minor things...QUITE out of character for this polite girl!!
​Still felt emotional off and on, and have had angry/highly irritated mood swings over nothing. 
​Threw up my coffee this morning but had no nausea. 
​I began heavily bleeding a week before my expected period, at 12 DPO, lasted a little over two days & still spotting at 15 DPO. This was accompanied by thin, watery CM that literally soaked my panties on the 1st day (12 DPO). 
​No sore breasts, very slight nausea (so slight could be imagination). I'm planning to test on March 22nd. Today I'm 15 DPO. 
​What do my ladies think?
