Ok so I’m a 19 year old female newly married. I’m having problems with my period and we’re not sure if I’m pregnant. I️ had a missed period in August , very late period in September , missed period October and November and so far no period in December. I️ have taken 4 at home pregnancy tests and 1 at the doctors office. They were all negative. I️ had every symptom of a pregnancy. Mood swings, morning sickness, etc. any ideas of what it could be?
