uhmmm question πŸ™‹πŸ»πŸ™‹πŸ»

Out of nowhere I just became incredibly nauseous. I didn't throw up or anything just a lot of spit but a few close calls. Still feeling quite nauseous so I took a gravol but now I'm noticing my lower abdomen/uterus feels a little tender. Nothing painful just discomfort.Β 
Me and my long term boyfriend have unprotected sex, we're totally fine if anything happens or doesn't but I just started my ovulation period today. So I can't tell if it's from that and I'm just having a strange episode or that there may be a slight chance of being pregnant? I've never heard of being sick in the late evening (10:30pm). Is that a real thing? Or is my brain just racing and jumping to conclusions.
Advice? Help? (If this doesn't change I'll be taking a test next week)Β 
Really appreciate it ladies! 😘❀
