Venting Post

I'm 7w 4d. 2nd pregnancy, 1st baby. I MC'd last July, and it's taken this long to get pregnant again. I have PCOS and a blocked tube. And I'm terrified that something is wrong. I have nausea occasionally, not as bad as it was. I've got gas, have had constipation. Sore boobs, and apparently able to smell EVERYTHING. I can't even say I'm not having symptoms. No bleeding whatsoever. I'm just irrationally afraid of a missed miscarriage or a blighted ovum. 1st doctor's appointment is 10/1. I'd really like some reassurance that I'm not the only crazy lady doing all of this foolish worrying!
