Pregnancy symptoms or am I going insane?

I have PCOS, and take Metformin daily, and letrozole on CD 3-7.

I have been carefully watching what I am eating (no added sugars, gluten, and low starches).. and on 2& 3 dpo I was feeling SUPER bloated.. and has continued all week..

• my boobs have been feeling super heavy&full; this week, to the point that they’re starting to get sore..

• last night I suddenly got a cold, and it carried into today..

• today around 9pm, my husband and I were watching a movie and I suddenly got extremely nauseous.. so I asked him if he felt sick (just in case it was from supper), but he said he felt fine..

• also, this morning.. my husband and I were having sex, and it was suddenly extremely painful, like he was hitting my cervix, but normally I don’t noticed any of that.. maybe my cervix is swollen?

So what I am wondering is.. has anyone with PCOS or not, had similar symptoms/situations to me, and ended up being pregnant?

I am only 6dpo, so it’s WAY too early to test.. and I am planning on testing on 14dpo. But now that I am on my tww, every little thing that goes either right or wrong.. I over analyze it. So any help would be much appreciated!
