i had a surgical abortion in december and now its february and my period has not started normally

though i have had sex with my husband which gave concern to think that i was pregnant,

i went to the hospital ,after the test i was not pregnant,

but i feel like am pregnant.my breast are bigger,my tummy is bloated i have also gained a lot of weight

and i also eat a lot.so the doctor asked me to come back after three months if my period does not come.

i need help because i don"t know what his wrong with me.
