I've taken home pregnancy tests and online pregnancy tests. The home one I took came up unknown the second line was very very faint almost not there. The online ones showed I have a high chance of being pregnant. My pants are snug and I have early pregnancy symptoms. Could I be pregnant?

Sure why not.

Any time there is penile insertion there is the possibility of pregnancy. I don't know what online test you did, but no online test can determine pregnancy. Taking them is a waste of time.

You mention early pregnancy symptoms, but you don't mention the most important one. When was your last period and when is/was your next period due?
