Pain and spotting for days…

I am 5 weeks and 1 day and have been spotting brown (and some stringy, clotty pieces) off and on for almost a week now. It happens almost every time i go the bathroom and wipe. It also has an odor. They also told me to get some Monistat cream for what they think is a yeast infection, but never even looked at to diagnose. I’ve never had one, so I don’t even know if that’s what I have.

My HCG levels continue to more than double (438, 990, 4915) and my progesterone is good (30), but is this normal??! My lower abdomen always feels like a dull pain or just tight, and I seem to have round ligament pains when I move quickly sometimes. Is any of this at all normal?? Have you experienced this? My doctor doesn’t seem to think it’s an issue and won’t bring me in until after 6 weeks since they “can’t see anything yet at 5 weeks”. I’m so worried I have an infection or something that will harm the baby, but they don’t seem to care. This is my first pregnancy that has progressed, so I am just scared and not sure what to expect. I just feel so off.
