Plan b twice in two months

Ok so I know there is a ton of forums and stuff that say all this c**p that can seriously scare the c**p out of you to make you believe that your pregnant but I'm here to be the girl to calm your nerves! So in the month of October I had just finished my period then had sex on the 7th it was unprotected and not being on birth control I went and took plan b the next day, a week later I got withdrawal bleeding due to the plan b. Two weeks later on the 21st the condom came off inside me and he had already precame. So again I took plan b and again a week later I got the withdrawal bleeding. I was expecting my period to come the first week of november and it did not come which freaked me out since my period is extremely regular. But I waited a week because I was aware that it could delay my period but a week later still nothing! So I took two pregnancy tests and both came out negative. Now that calmed me down but day after day kept passing and still no period! I started freaking out that maybe the pregnancy tests were wrong but let me tell you that there is only a 1% chance that they are wrong if you take it after your expected period and you probably read a ton of those girls that were like I got a false negative before but most likely they took there tests too soon or theydidnt take it correctly or they were apart of the 1% of the population that doesn't produce alot of hgc. If you are a girl that has regular periods BELIEVE THOSE PREGNANCY TESTS! don't stress out it'll delay you even more! I ended up skipping a whole cycle and yes it was the most stressful month of not having a period! But now looking back it makes sense that my period skipped because plan b is just birth control pills and what do birth control pills do they make your body think that it is pregnant so basically plan b is like being on birth control then coming off ( though it doesn't protect you the whole month) but I'm talking hormones wise. Also the withdrawal bleeding is usually a good indicator youre not pregnant since the spike of hormones from plan b makes your body think your pregnant then it decreases and basically your body has like a fake miscarriage. But seriously don't listen to all those scary forums if you took plan b correctly your chances are seriously zero to nothing to being pregnant!
