No period 10 weeks after MC

Stephanie
I found out I had miscarried on 14th Jan at 10 weeks.
I started bleeding the week later and had a scan at Early pregnancy the end of Jan and was told I had passed everything and we could try again, no cysts or anything.
Since my miscarriage I have not had a period Iv had a tiny bit of spotting and had dull warm pulling feelings near my ovarys. I have took numerous hpt but getting a negative result. Most days I feel sick and get a sore head.
Has anyone who has had a miscarriage waited this long for a period to return? I feel like my body is tricking me with the symptoms I have :( 
Sorry for the bad grammar and spelling.
Thanks 💖
