Am I testing too early?

Jasmine
I need some advice. On Dec. 30th my bf and I had sex. I wasn't sure if I truly was ready for a baby and decided to take the Plan B pill. We had sex again on the 6th of Jan. and I decided to follow through. If we were pregnant great if not that was fine too. I had cramps a week or more before my period which is very unusual. On the 13th, it was shark week.lol My period came a bit early in my opinion but I don't track them although I do know they are irregular. It lasted for 3-4 days. From the 16th-the 25th we had sex basically every day. Being that I don't track my cycle, I'm not sure of my exact ovulation day or fertile days. I believe my period began between the 17th-19th of Dec. I have been going with the 19th since I know for sure I was on that day. That put my cycle at 25 days so I calculated my ovulation day as 21 Jan and fertile through the 26th. I've tested on the 29th-today with all negatives. I'm expecting shark week between the 10th-17th (basing it on a 25-29 day cycle). Could I be getting negatives because I'm testing too early or can it be correct? I'm getting pretty excited now to be a mommy and if negative, I'll be pretty upset. I've been using First Response tests. Any advice would help! Thank you! 😊
