hi to anyone who could be of some assistance. I had unprotected sex on May 31st, the week of my ovulation. Then the next week or so I began to feel extremely bad and nauseous. But I just figured it was because the week before I had unprotected sex I had to go to the hospital because I was dehydrated and passed out . However, I still continued to feel bad, some days I was amazing others, like right now I'll feel ugh , I'm cramping, bloated and extremely tired. To sum it up for you guys, my boyfriend finally texted me and told me he did ejaculated in me and I did not receive my cycle in the month of June at all, but today, July 6th, I received a bit of spotting. It was a light pinkish color and honestly I'm just wondering is that implantation bleeding or is it my cycle? How long after having unprotected sex does it take for implantation bleeding to occur? Also, any speculations as to why I didn't receive my cycle last month if I am not pregnant? Thanks in advance. God bless.
