Could I be?

Chelsea

So lil bit about myself. I’ve been diagnosed with PCOS since I was 15. I’m a couple years older now. Anyways my fiancé & I decided in May we was going to start trying to start a family. I took 2 pregnancy tests 2 weeks after trying because I just couldn’t wait any longer....of course they ended up being negative😔. August was our last session because he’s been out of state working so we haven’t been able to see each other. But I have been sick every morning & every night for at least a month. Is there some possible way I could be pregnant & the tests aren’t showing it? 😳 I need some major advice from a cyster. Thanks a lot
