Yeast Infection & Possible Pregnancy

Julie • Hello! I am 26 yrs old & TTC first child with PCOS.
I have recently developed a yeast infection about 2 days ago.. It's not bad, it's actually pretty mild but I've also been having pregnancy symptoms. Is it okay to treat a yeast infection with OTC suppository? I have already started the medicine but thought I would double check with the women on here to see if anyone had any issues. I just assumed it would be okay since most pregnant women get them anyways. Also, will this affect the outcome of any hpts I take? I don't think it will but again, double checking. 
**preg symptoms include:: lower abdominal cramping (light) with twinges and pulling feelings occasionally, lower back ache occasionally(more often than not) increased appetite, fatigue (I NEVER nap and have seemed to have napped every day for the past week) irritability, and slight constipation started yesterday and had it today as well.... ** 
Any thoughts or shared experiences???
