<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi Im 19 years old and my boyfriend and I have had unprotected sex multiple times while I was ovulating . I usually get my period from the 12th to the 17th or so but this month I had it usual time but then also had some spotting on the 19th to the 23rd . But Im worried that I am pregnant . Ive felt kind of nauseas , and not very hungry . And Ive also had a weird crampy feeling in my lower stomach . My boyfriend also says Ive been having mood swings too .  <response>: HI, Thanks for the query. I understand your concern. Having unprotected sex many times during ovulation your pregnancy like symptoms suggest strong chance of conception. This time you had unusual bleeding after menses. This can be due to- - both bleeding regular menses the spotting after wards can be hormone deficiency with early pregnancy Threatened abortionIrregularity in period out of physical stress or psychological anxiety fear about conception. Hormonal imbalance causing menstrual irregularity. The Home pregnancy test after 8 days of the menstrual date USG scan after 3 weeks of ovulation can give exact situation. Consulting a gynecologist for physical examination immediate treatment in case she suspects pregnancy is advised, Repeat menstrual irregularity needs investigations to find out the cause specific treatment. Thanks.
