Hello, thanks for writing in.
From your post I understand that you have conceived, but nothing has showed up on the
ultrasound.
In order to say if this is abnormal or not, I need to know how many weeks after your missed period date did you test and if it was a transvaginal scan, as by 6 weeks a sac must be seen.
Mild spotting and cramping can be seen early on, but you have mentioned that the amount of bleeding and cramping has increased. This raises a red flag.
In such a case, I would like to rule out an abnormal intrauterine or an ectopic
pregnancy. Talk to your doctor about these possibilities.
Usually follow up scans and
HCG levels are done along with clinical correlation.
If all seems ok, you can ask him/her about the need for
supportive medication.
I would suggest you consult your doctor at the earliest.
All the best.
