So I had protected sex w my ex boyfriend on my fertile week last month. None of the condoms broke and I am not on BC. I took 5 pregnancy tests and got all negatives. A few days later my period finally came. It lasted 5 days and was slightly heavier than normal. I’ve been stressing a bit about the whole thing since my period ended. I took another test and also got a negative result. There’s no possible way I could be pregnant ?
