Implantation bleeding question. My fiancé and I have been TTC for about 3 months now. I have a very irregular cycle and *may* have PCOS (don't know for sure as I haven't gotten a full work up and my gynecologist said it may just be weight related and go away once I lose some weight....). Anyways, I had a period from July 19-25 and then not again until September 21st. However, that one lasted until pretty much October 18th (switched between light spotting and heavy bleeding for that whole time). It officially ended on October 18th and my fiancé and I have pretty much had sex every day since then (besides 2 days). We also had sex random days during my 3 week period as some days I was barely spotting so we took advantage of that. I use the ovia app and according to the app, I can take a test in 5 days. However, Sunday afternoon I went to the bathroom and there was light pink on the toilet paper. It was only that one time and that was it. Monday was completely normal and then around 1pm, I started feeling kind of crampy and went to the bathroom and had pink spotting again. By 4pm, it had turned red and I put on a pad. I had pretty decent cramps for a few hours too as well as lower back pain. I had originally thought that maybe it was implantation bleeding but from what I understand, it's usually not heavy or red. The bleeding completely stopped as of around 7pm. So pretty much from 1pm-7pm, it went from pink spotting to red blood to light pink again and then nothing. Yesterday (Tuesday), I woke up with bad cramps and took two Tylenol. I wiped and again there was a salmon colored spotting going on. It was on and off all day. Today (Wednesday), I woke up to some brown spotting and as of now, it's light pink again. Is there any chance this could be implantation bleeding? I'm confused about all of this as it doesn't seem like a period as my periods are normally very heavy and also, I never get cramps at all. Sorry for the long post but I'm just so confused!
