i took Plan B in July and got my period 3 days later than expected, and it lasted 8 days long. in august, when was due to get my period, i experienced heavy spotting with a lot of blood clots. it was pretty heavy the first two days, some bright blood but mostly dark red/brown blood with a lot of clots, then got much lighter. it is what would be day 5 of my period and I'm experiencing very light brown discharge. my breasts are tender and feel heavy. my boyfriend went in for not even three min without a condom at the beginning of august. am i pregnant or is this plan b still affecting my cycle? I've taken three HPO and they have been negative but I'm still scared.
