Period or no?

Hey! I havnt had a real period for like 3 months now :( this month on Saturday I woke up and my underwear had like blood on it (tmi I’m sorry) anyways we where in a motel so I had to go to the store get some pads and change underwear. Anyways the day we went to a zoo and enjoyed family time when I got home I went to the bathroom and nothing was on the pad or when I wipe.. Sunday there was nothing, Monday I bleed once when I used the bathroom and after that nothing, today (Tuesday) there is nothing! I have symptoms like I have been moody, my back is killing me. Right now I have a head ach and I been feeling awful like cramping and feeling down and depressed just like I normally would in my period.. I’m just getting frustrated because I want another baby but I don’t know now if I am even having a period.. like would u call this a period?? I don’t have PCOS but have something similar. Metabolic syndrome so idk if I can even have another baby 😭I’m suppose to take metformin but can’t that medicine makes me sick! I’m also suppose to take vitamin B12 and D but I havnt been taking that either. Anyways my daughter is 3, I’m not on birth control never been on it and we don’t ever use condoms. It was hard getting pregnant but I was having a period every month so idk what to do now :( just want to cry😭😭😭
