Chemical Pregnancy Questions

LK
Hi ladies, I had a MC last January at 13 weeks and am now just suffering a chemical pregnancy at 4 weeks, 4 days. I have a few questions maybe someone can help me with since my doctor's office isn't in today:
1. Can I wear a tampon?
2. Does this count as another MC or do I consider this CD1?
3. How long before we can try again?
4. Any restrictions on sex, bathtub, etc after the bleeding stops?
5. Should I ask for testing at this point?
6. Was prescribed progesterone once they saw my levels were low. Do I stop taking it?
Obviously, I will also ask my doctor these questions this week, but am wondering if anyone can shed some light on these questions/give me advice today. Thank you!
