Pregnancy symptoms help !!!!!!!!

I had nexplanon put it March 10th and got it out April 22 because it started making me nauseous out of no where me and my fiancé were having un protected sex the whole time I was on it and he finished inside me 2 times (tmi) ever since then the nausea still hasn't gone away I have craving but 2 pregnancy tests were negative now that I have it taken out the nausea has gotten worse I'm bloated all time and I feel weird movements sometimes idk if I'm just making my self feel like this because I want a baby but it's gotten to the point where I could hardly eat without gagging ...
