<s>[INST] Ok so on Saturday my girlfriend came over to my house. We did some freaky things and she stuck the tip in. I didn t have an orgasm but I m still scared. The next day she had her period. It is now Wednesday when I am typing this and she said she feels sick. Since she left my house she said she had heart aches., felt dizzy, wanted to throw up, and says shes never felt a stomach ache like this. Can my girlfriend be pregnant? She also says that she thinks she s sick because she accidentally ate old candy on Monday, but I don t think its the candy. She is now telling me she had heavy blood flow on Monday morning, like she stained the bed. [/INST] Hello dearI understand your concernPeriod followed by the unprotected sex does not cause pregnancy.Heavy bleeding after the sex could be due to infection/inflammation in cervix, vagina, polyp or any growth in cervix and uterus, cervix/endometrium dysplasia.Throw up, stomach ache could be due to stomach infection.Dizziness could be due to blood loss.I would suggest to consult the gynecologist and undergo vaginal examination, vaginal swab test, USG scan,  PAP smear/colposcopy to rule out the cause.Specific treatment will depend on the cause.Bleeding can be reduced by the progesterone pill.Take tablet meftal spasMaintain proper pelvic hygieneTake proper rest, eat healthy diet with iron supplements.Hope this may help youContact further if follow up needed.Best regardsDr. Sagar </s>
