So I had my last period 11/14. It lasted until11/16, which put my most fertile period right around my birthday (11/28) I had sex (condom as preventative method) on 11/27 and 11/28, and didn’t notice anything different right afterwards and neither did my boyfriend. I know however condoms aren’t always 100% effective. So go into December, and my CM was all over the place I went through probably every phase. Around the time I should have started a period, I just had cramping like it was coming. My period usually comes two days after my roommates, but nothing. I figured I’d get it when I went out of town. Still nothing. I came home 12/22 and had cramps and such until 12/23, which that night I felt like I had a cold or the flu. Had that for about 3 days, and today I woke up and took a test and it was negative. I’m now about 18 days late from my missed period and I have seen signs of brown discharge and what seems to be spotting? Could that be implantation bleeding and could I just be running a little late if I were to be pregnant? (if that’s a thing) I’m not TTC, but I just feel like I have had every symptom and sign.
