AF due 4/4 and feeling sick, should I test?

This is my first month using glow, ttc #2 AF due 4/4 and I am 11dpo and I am feeling nauseous. I prefer to fall asleep lying on my stomach but the last few nights it has felt uncomfortable. I was tempted to buy an frer and test first thing tomorrow morning but then I had some slight cramping last night and decided against it. I haven't told anyone I am ttc because I don't want the pressure each month of questions about if I am pregnant but I would really like someone to discuss it with. Any thoughts or advice would be gratefully received.
