AF was due May 15th and I had multiple intercourse with no protection, I thought for sure I would be pregnant since af didn't show on May 15 I took a test but it was negative and then may 16 af showed up .. But it was irregular I had it for 3 days and just spotted on the fourth day, after that we started trying again . Today I took another test because I thought it could be a false negative from before but I got another negative 😕
