What to think..

Katie • Hello all! My name is Katie and I have been married to my husband for 2 years. I have pcos and TTC.
So husband and I are ttc.. But I've been having some symptoms, not sure if it's pregnancy symptoms or pre-period symptoms. 
My nipples are tender/sore to the touch
I've noticed that I've been gagging the past couple of days on normal things (like taking Tylenol, chicken from dinner eat)
Maybe a little cranky here and there
Emotional
What do you ladies think?
