😧😧I soooo messed up...

So about a couple weeks ago me and my husband had unprotected sex (which we don’t normally do. 😂 I️ already have a 5 month old. And my period is normally very accurate, except the first month after having her. Well I’m officially late and I’m kinda freaking. There’s no sign of my period at all, I’m not having cramps or being super tired or hungry all the time like I would normally be a day before my period. 🤦🏼‍♀️ although I was super sick and throwing up the other night and I’ve been having bad headaches a lot lately and that’s a pregnancy symptom I had with my first. I’m too scared to test and see. Has anyone had their pregnancy symptoms before without being pregnant?
