SPOOKY nipples/pregnancy scare??

So after my boyfriend and I were messing around in his van (no serious genital contact but it did get pretty wet and we weren't super careful) I started getting super paranoid. It was around my ovulation time and we weren't protected (even though pregnancy is super unlikely without penetration).

What was REALLY freaky was that my nipples started tingling about four days after! Not only that, but they were a weird color and my montgomery glands were showing. This has never happened before. I always read online that this was a first sign of pregnancy, so naturally I became terrified (I'm way too young and I go to a Christian college). My boyfriend tried to reassure me that I wasn't pregnant but I still was shook.

A week later, my period was late. I thought it was the end of the world. I completely missed my period and cried a little.

PRAISE GOD today I got my period (6 days late)... but anyone know what was up with my nips?? Super weird. I guess tingly nipples doesnt always mean baby 👍
