Plausibly Pregnant after almost a year and a half

I got pregnant 2.5 months after getting married when we were intentionally using the withdrawal method, so we were open to the possibility but preferring to hold off a few months so I could graduate on time. We started trying for our second when she was 14ish months and conceived the very first month trying. 4 days after a very faint positive and 2 days the BFP, I started spotting with cramps. Got put on all kinds of progesterone, but baby was measuring 6 weeks at the 8 week ultrasound, so it was never normal. I miscarried 11/17 at 11 weeks and we’d been trying ever since. This was my third and possibly last cycle on Clomid (my obgyn likes to do 3-4). I’ve managed to convince myself that maybe I am actually pregnant finally every month, but always start. Symptoms have not been very different this month, and I’ve had cramps even today, but not spotting. It’s only day 28, but tested yesterday because I could. Imagine my surprise when there was a faint positive, but not one I have to squint to see, so probably actually a positive this time!!! (Past few months I squinted enough to convince myself lines that weren’t actually there were present). Tomorrow I retest and then again on Wednesday to make sure. I scared by optimistic and extra scared that I’m optimistic because I’ve been here before and scared of miscarriage much more now. I coped very well with the first but we’ve wanted this baby so long and have been scared my daughter would never have a sibling. All the feels.
