I’m very confused and I need to know if anyone else has experienced this please :)

So I got my Peak fertility on Wednesday last week (31/1). OH got home on the Friday, we had a couple of BD sessions and on Saturday we also BD’d twice. I’m not sure when I ovulated, I’m assuming either Thursday or Friday.

We are now at Sunday and my boobs have gotten really sore. Tingling nipples were a sign for me to test in my last pregnancy, and I got a clear BFP, 12dpo.

I’ve read this could be a sign of implantation, but I feel like my hopes are getting up because we want it so badly.

I’ve got a feeling in my throat like I’m about to get a cold, and I also have upper back pain. Cried my heart out for no reason last night too 😂

Yesterday (Saturday) and today, I’ve had two low OPKs.

Perhaps I’m just getting sick, but I so badly want to believe it’s going to lead to a BFP.

Has anyone experienced this and gone on to get a BFP?
