So unsure..

I recently got off the nexplanon after a year of being on it. I got the implant taken out mid January. I've been tracking my cycle on Glow since November and it says I ovulated two weekends ago. My husband and I are TTC and had sex during ovulation and I'm having pregnancy symptoms: sore breasts, nausea, fatigue but both tests have been negative. AF is due in 4 days. Not sure what to do at this point.
