Possible pregnancy? 🥴

Late period according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> app. I don’t usually skip my period. But it does consistently come a few days earlier each month. This month, it hasn’t arrived even at the previous month’s time.

No symptoms at all. No cramps like I normally do, which is strange. I feel nothing at all.

My boyfriend and I did have sex without a condom. He DID NOT cum in me. Just precum. That was around Dec. 14/15, I believe it was during my fertile window though.

I’ve taken 2 pregnancy tests so far. I took one yesterday and the previous day before that. Both negative.

What are the chances of having a pregnancy? And when should I take the next tests?

Please help!
