Scared to hope for our Rainbow Baby

So... I had a D&C 3/18 after having to go to my second ultra sound alone because of quarantine only to find no heartbeat. It’s been hell. I am 44 as of June, divorced (thank God it never happened with my ex) and frankly didn’t even think I could get pregnant at this point. My boyfriend/soul mate (51, healthy, divorced and no children) and I found out we were pregnant accidentally and naturally on vacation in Hawaii in January. Since the MC we have been trying as my cycle got back on track. Right before my last ovulation I decided to start acupuncture and Chinese Herbs. Well the coming week contained my ovulation day. My BF and I did our best to make the most of it. By my appointment the next week I noticed my right nipple was annoyingly sore and since then my boobs feel like someone else’s but sore. And CRAMPS. Then two days ago (cycle day 24) I started spotting pink and brown. Yesterday bled on and off but light and thin. No clotting. I thought it was probably a period and didn’t get my hopes up. Negative urine tests up through today even though today is only cycle day 26. But now by then end of the day the bleeding has all but stopped. I also feel like I have the flu and threw up after pushing my boyfriends niece on the swing from motion sickness yesterday. I am using First Response early tests. I am FREAKING OUT and trying to remain skeptical but boy, I feel weird and the bleeding stopped so...... waiting for a BFP. 🤞
