Any advice?

Kaleigh
For starters, I am still bfing my almost 11 month old, although he has weaned dowb to basically naps and night time, with sporadic nips here and there through out the day. My periods started back in February, had one in March and April,and last one was May 6-9 and very light. Cycle has been pretty regular since starting, about 30-34 days long, but now I'm on cycle day 64 and NOTHING. Negative tests on June 19 and 21, and again yesterday afternoon. Having a lot of lower back pain, especially when bending, more pronounced veins on chest (which I seriously didn't think could become any more pronounced lmao) nausea on and off for a week or 2,period like cramps , severe mood swings. Still no sign of af. Anyone else going through this or have a similar experience? Should i test again? Blood work? Still regulating? Any advice or comment would be appreciated! Anyone?
