It's coming...😔😭 threat of miscarriage?

I've had 4 very light positive hpts since Sunday, but when I checked this morning expecting darkening lines my first response was still faintly positive and a new Clear Blue Digital read "Not Pregnant". I tore that test apart trying to see the strip inside and understand it. A few hours later I was in the ER checking if it was viable & the possibility it was ectopic because I'd been cramping for days. My bhcg came back at only 10. My ultrasound (too early to reveal a sac) showed free fluid around one ovary and a "hemmoragic corpus leutum cyst" on the other. The ultrasound couldn't show a sac or rule out ectopic because I'm only 4 weeks 2 days. I took clomid for the first time this cycle which explains the ovaries, but not the low hcg. I'm terrified the clomid worked (in terms of making a viable egg, it just maybe didnt implant great) but also caused the ovary issues and my OB might not let me use it again. The OB on call happened to be my OB so the ER doc consulted him and he said the # was low but it could just be really early and "only time will tell." I'm going back for repeat hcg testing in 72 hours, and waiting to see if bleeding or more intense pain occurs. Now I have a headache & I can't decide if it's from a lack of sleep, falling hormone levels indictating miscarriage is imminent, or from staring at my phone all day googling things like "hcg of only 10" or "hemmoragic cyst" or "cramping at 4.2 weeks without bleeding" or "pregnancy test sensitivity" or "headaches before miscarriage". I'm just feeling lousy over here, wondering why it seems like having children is the easiest thing in the world for some people and impossible for me. SCORE SO FAR: stillbirth:1, possible miscarriage: 1, live children: 0.
