My cycle is normally 34/35 days ... tested on Sunday on day 34 and got a

result
Still no period and now on day 38. My boobs are sore, nails growing like crazy and very strong. Was sick 3 or 4 mornings last week, been feeling tired and been getting cramps for 5 days like on my period but no sign of bleeding.
I have been pregnant twice before but sadly both ended in mc, was 6 weeks the first time (as we weren't trying so never crossed my mind I was pg!) and the second time got a positive test at 4.5 weeks.
Do you think I could be pregnant? Too scared to test again in case it's still negative.
Anyone else had similar symptoms and got a

?
