I just wanted reassurance since I'm having anxiety attacks lately (which I'm trying to control by not reading into stories here) but then I see people who gets pregnant and still had their "period"

The last time I had sex was back in March 11. My period that time was 4 days late. Then comes my april period, 2 days early. Then my May period comes 4 days late again.

I did a test and it was negative. I know I'm not pregnant because its been months since I had sex and I would def get a positive by now but I just want to ask for some advice. I want to not be scared if ever we're gonna do it again. I mean come on, abstinence is ruled out. I just want suggestions, like are condoms 100%? birth controls? implants?

no hateful comments pls thank you.
