8 weeks nausea gone?!!

Rae

I am currently 8 weeks and ive had pretty consistent nausea since 5 weeks. Its been 4 days now with no nausea.. My breast are still tender but other than that i dont feel pregnant now. Ive had 2 ultrasounds with heart beat detected. 6 weeks 5 days fhr was 142bpm and 7 weeks 2 days fhr 158 bpm. Should i be worried? I cant help but worry!!! Next appointment isnt until the 5th of march!
