TTC & odd symptoms

I’m currently 4 DPO. We bd 3 days before, day of and day after what Glow says is my ovulation. I’ve had nauseous feeling with certain smells. I can’t hardly eat w/o feeling sick. I’m emotional and I feel bloated! I know it’s obviously too early for any pregnancy symptoms but I’m driving myself nuts. Any opinions on what’s going on. **side note. I know I need to use OPKs and not depend on glow but that’s all ya girl has for rn.
