I had a baby 11 weeks ago. I had my first period on 21 May and it lasted 5 days like normal, it was heavier than usual but that was all. I’m exclusively formula feeding. My cycles are generally 28-32 days, so the latest I should’ve started my period is 2 days ago. All the tests I’ve taken have been negative... so is this just normal for after birth or should I wait to take another test? We’ve been using condoms but on the odd occasion have had unprotected sex for a few minutes before putting the condom on.
