Hello, My question is me and my boyfriend had an oral sex during that time he touched my vagina with his penis but it was all dry and he didn't come in. After like regular menstruation I had my cycle. Then I have got another one in the in the next month. On the third month I have got another menstruation but it did only last for two days where as my cycle is for five days. I'm confused, is that a sign of pregnancy or its just normal. Please let me know. Thanks!
