7 losses, 3 in 6 months

So little back story, I’ve lost 7 pregnancies all between 2009 to this year. So over 10 years. I lost 3 the last 6 months. Two back to back May and June. I’m on CD38. No signs of my period coming and no positive test. I have every symptom of pregnancy even a change in cervical mucus. Anyone every go this long with no period and turn out pregnant? Like you ovulated super super late after a miscarriage? It was a chemical so my period should’ve returned like normal like it did after my chemical in December. Ive only had 3 chemicals before and all since December. The other 4 losses were late 1st trimester losses.
