ok so june was the last time i had sex(protected)...but after we finished we noticed a huge wet spot on the bed (we never established how it got there or who made it)....i have P.C.O.S. so its hard to determine when my menstrual period is going to come...i did have a normal period after sex...but today i had some spotting occur when i went to the restroom but on a normal 28 day calendar my cycle isn't due until 8 more days...... and the spotting lasted for like 10 mins......ive heard of implantation bleeding and was worried that this could be it. what do you think? (we are not sure if the condom had a hole in it and he also says he didnt get to cum..but i also think about the precum)
