So me and my boyfriend are TTC and we had unprotected sex two days ago and he came inside me. About 4 hours later I went to the bathroom and I noticed some spotting and I was told it's too soon for implantation bleeding and it was probably just from sex or the last of my period. I had just got off my period on the 5th so I know I wasn't ovulating yet on the 6th when we had sex. Well today I just went to the bathroom and my discharge was a milky white with a touch of red so I'm guessing I'm spotting again today. Could this be implantation bleeding? My periods are really irregular and me and my bf have been trying for almost six months.
