First Sonogram 5wks, 2days

Rochelle • I`m a 30 year old Registered Nurse. My husband and I were married in August and are excited to have gotten our BFP. Baby Alonzo is due in June.
So yesterday I had some mild cramping and spotting so my OB had me go have hcg and progesterone levels checked. My hcg level was 2100 and progesterone was 9.4. My progesterone is on the low side of normal. They called me this morning and wanted me to go in and have ultrasound performed. I'm assuming to ensure it wasn't ectopic or a blighted ovum. I just finished the ultrasound a bit ago. I hate having to wait until Monday to get the results. The sonographer did tell me she saw the gestational sac and yolk sac. I'm worried about my progesterone levels though so I bought some OTC progesterone cream to use until my OB decides what she wants to do. Anyone ever used OTC progesterone cream?
