so I’ve had unprotected sex this month and last month, last month I had it one day on ovulation but then I had a “period” it was like 3 days long when usually it’s about 7. Then this month I had unprotected on the last 2 days of ovulation, im about to start my period in about 3-4 days. but im constipated having night sweats and just cramping and feeling like im gonna throw up when i crap is this a early sign?
