Pregnancy symptoms or am I going insane?

So.. here’s a bit about me first (sorry this is a long post.. 🙈)

- I’ve had PCOS for 10 years; but only recently started trying to get pregnant (so only been paying attention to ovulation for 12 months).. and don’t get a period regularly/at all..

- I have been seen by a gynaecologist.. and he prescribed me with Metformin (500mg in morning, and 500mg in the evening) to prime my ovaries, and then on CD 3-5, I take Letrozole (this last month I started 7.5mg).. and I FINALLY produced a good sized follicle! (I have been doing this type of treatment since October 2017.. 😔)

- So, my gynaecologist told me to BD lots on CD 15 for sure, but to do it as much as we could, just to make sure we caught my follicle. 🤞🏼

So fast forward to this past week.. and the stuff I am SUPER confused about..

** I know that everyone is different, and has different experiences with symptoms and such.. just looking for some success stories and positive opinions please **

• 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!
