Anxiety about being pregnant

Hi! So, this is going to be kind of long but to start off I have anxiety. So New Years <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> 2019 I had protected sex and used the condom correctly. It was a tight on him is all but it didn’t break. I took a HPT two days before my period was suppose to start and it was negative. Got my period a day late. (Maybe Bcs of how bad I was stressing). And then my period lasted six- seven days. I took another HPT the second to last day. (Anxiety) That also came back negative and I have gained about eight pounds to date. So yah that’s my story. Plz leave comments that may calm my anxiety Bcs I am still partly worried that I am even tho that is nuts. I have read about other blessings during pregnancy but they are not like a period.
