I've been feeling pregnancy symptoms since the end of may. My breast have been sore, boobs swollen, back hurts, Going to the bathroom all the time, sleep pattern is very messed up, very hormonal, very horny, my period has been very weird (yes still getting it), negative test. My mom and sister are convinced I'm pregnant. But I'm worried because I'd be almost half way threw the pregnancy. Is it possible for me to be pregnant?

I've also gained weight and I'm barley eating because I've been sick

What do you mean by "your period" how is it not normal ?

If after 4 months you are still getting a period, I would say you are not pregnant, but could have some other illness or problem that should get medical attention.

Also if at about 4 months you are getting negative test readings, I would say you are not pregnant.
