What should people pay attention to in terms of crowd flow?

Patient's question:

Doctor, hello
A few weeks ago, I had an abortion. At the time, the doctor advised me not to have sex for a month, but my husband and I didn’t listen. We had sex after only about ten days...
I’d like to ask, what problems could this cause? Will it be serious? I’ve been very worried. Please tell me what I should do in the future and what I should pay attention to. Thank you

Doctor's answer:

It is very easy to cause gynecological inflammation, so it is important to pay attention and avoid sexual activity during menstruation and postpartum. Pay attention to hygiene.
