Pregnancy & depression

Hi ladies. I am currently 20 weeks +2 days. This year has been a lot of change for me from getting married, an ectopic pregnancy, moving to a different state, and getting pregnant again.... Since getting pregnant I have been extra moody & distant from my hubby. And my moodiness has gotten better but I find myself In bed most days missing home, and just too tired to do anything g with myself. I work part time 13 he days and pull it together nicely for that but the rest of time I can't figure out if I'm depressed, just home sick, lonely , or what. I know I love my hubby but I can't even show him love....  I don't like to even take Tylenol so the thought of taking meds while pregnant scare me. But I'm not healthy n that can not be good for our baby. I guess I'm just looking for some advice and to vent and not to be judged....
