Yesterday fmu

Today smu

I got a decent but fainter positive hpt yesterday after a decent temperature rise. Today my temp went back down and I'm nervous. I've looked everywhere for reassurances and I even retested this morning, but I was trying to wait until tomorrow so I ended up using smu. Yesterday's was fmu and it is only barely stronger than today's smu so I'm trying to cling to that for hope. We've been trying for years and had a mc last year at this time on my birthday (Nov.12) and I'm trying not to freak! But I'm scared its going to happen again.
