I’ve been on the combo pill for years, i had sex on my placebo week about 2 and a half weeks ago and I’ve been experiencing breakthrough spotting for 5 days. I was late to taking some of my pill, i never missed any, but a few hours late.. is that enough to make me have spotting? I’m so worried it’s implantation bleeding.

I have taken 4 pregnancy tests: all negative, still worried.

Please help.

Especially if this has happened to you on years of birth control.
