I feel crazy

according to my old app I ovulated on the 19th, but on this app I ovulated on the 20th.

my husband and I had sex on the 20th unprotected.

for the past few says (since Monday) I've been feeling groggy and tired.. and today I have barely left my bed.

my nipples itch sometimes. but my breasts aren't sore and all I've really gotten so far is fatigue, cramping and alot of smelly poops..

I feel like I'm going crazy because it all can mean anything and I still have a week before my period.

anyone have any thoughts?
