1ST PREGNANCY?

Anyone on their first pregnancy feel just straight like they’re going to start their period but have ended up pregnant?? I’m so confused because I’ve had stomachaches from foods that usually don’t bug my stomach. Also acid reflux for 2 nights when I lay down. Burping a lot, and my PMS but having not just that burning pain but some sharp pains here and there and extremely bloated. And my lower back pain is intense, it’s hard to stay sitting for a long time. Did anyone else have these and pregnant? I don’t have sore boobs as of now but I hear not everyone gets every symptom. Just wondering if I’m not alone. !!! ???

I’m 5 days until my next period and 9 days DPO but I don’t feel like I have symptoms enough to test yet. Headache and slightly nauseous. But faintly nauseous on n off only. Should I wait to miss my period still ???

Thanks in advance 🙏🏼
