Late period after two iuds

So, I’m 6 days late. 8 negative pregnancy tests.

In October my iud came out. I had one reinserted two weeks later. That one came out two days after inserting. A lot of uterine lining came out with both. My dr advised me no more iuds.

I got a normal period in November.

We’ve been using condoms while we wait for my husband’s vasectomy in January.

We have not had unprotected sex or sex much at all because I don’t want to be pregnant right now.

Up until a few days ago my cervix was hard and low. It’s now still low but soft. But, tests are still negative.

I do NOT have insurance until the first of next month. So, I guess I’ll go in then.

But, anyone have any experience in the mean time?

On the day my period was supposed to arrive I had what was almost like the flu. I couldn’t stop puking and I had body aches and sweats. It lasted two days. Now I’m just constantly cramping and feeling like my period is starting but then it doesn’t.

I am breastfeeding but for the past 7 months my period has been on time.

Thanks!
