Apologies for the long post, there is some tmi information ahead. We are not actively trying to get pregnant, but my nexplanon implant expired end of April and I couldn't get an appointment until 10th June to replace it. My cycle is very sporadic due to endometriosis (28-80 days) and I'm sure the expired nexplanon will have thrown things off a bit. We have been a bit reckless when it comes to alternative protection.
According to my cycle tracker I would have ovulated around the 3rd May. I took my kids swimming on Sunday afternoon (I basically stood in the shallow end supervising, as my youngest is not an independent swimmer) and noticed pink discharge on the towel after, this would have been approx 8dpo. The next day this increased a little, some spotting in my pants, but mostly when wiping. Yesterday (approx 10dpo) this was slightly more again, but with a little brown spotting and today it has stopped completely.
My cycle tracker expects my period on Friday, and today is cycle day 35 (if going off my last period.) I took a FRER yesterday and today, which were both negative. However I'm unsure if I can rely on the result due to my sporadic cycle. I am considering if the spotting was implantation bleeding or a very short/light period. If it was implantation then could it still be too early to test even with early detection tests, despite my period being due in the next 2/3 days?
I've been having symptoms which could be either early pregnancy or simply premenstrual. (Waves of nausea, cramps, back pain, breast pain) How long would you wait to test again and consider a negative test to be conclusive?
