So my last full period was like 80 days ago, March 1st. I wanna say I had sex on my most fertile day and a day or two after. The next period that was supposed to come was EXTREMELY light like very out of the blue for me. So I’ve been taking tests since then, they were 100% negative. Then about a month after my very night period I had two super super light lines. Fast forward I’ve still been taking test and they’re negative. However, my lower back has been killing me on the left side and for the past week my nipples have been quite sore. If any of you have been through something like this or know anything I would greatly appreciate it✨💜
