Hello and a question about spotting

petite chouette

Hi ladies. I used to post on IF and 3T, but I was pretty depressed after my last loss and had to take a bump break for a bit. Anyhow, I am very cautiously resurfacing with a hello to each of you lovely ladies. I have been praying and cheering for you all along.

So, my question... I got my bfp last Monday after an FET. Beta at 8dp5dt was 336. I'll have another beta on Monday. Since yesterday, I have had very light pink spotting and AF-like cramps. Google tells me this can be normal, but I am still concerned, as it seems late for implantation bleeding.

I will feel better hearing from the PAIF ladies -- did anyone here experience this?
