"well, like many here i sat here and went through all these reviews at least twice probably more. september 8 was the start of my period then on the 18 i committed the act with the bf. chance of pregnancy definitely minor but i was paranoid so he purchased the plan b one step. for approximately for 15 days i had light cramps and i do believe i also acquired a uti. i was also fatigued had headache here and there and also had diarrhea tender breasts and on the 15 day today mother nature graced me with aunt flow. i am also way over the weight by at least 10-15 lbs over actually so the weight limit don&#039;t even worry about it. but when your period comes prepare yourself for some cramps"
