The Teen Mom 2 star, 26, went on Twitter on June 2 to tell fans about her aborted romances.
First, she discussed breaking up with Potter in January after a two-month relationship.
Lowry tweeted, "Dom & I dating - I wasn't trying to deny her or a relationship. & we had fun while it lasted but things didn't work out. I've learned a lot over the years and wanted to keep things private & off the show but i don't think i really handled it properly."
The reality TV star then dealt with her brief reconciliation with Marroquin, writing for her second main point, "2-Javi & i talked about getting back together at one point. Why? I don't know because we both knew we didn't want to & it would never work. I regret even having those conversations. I regret filming about it. And hooking up w him as i know people from the reunion leaked that."
Lowry wished her ex well, as he's now expecting a baby with girlfriend Lauren Comeau, tweeting, "I am wishing him and his new family the best. I have no hard feelings about the baby whatsoever despite what people are saying."
The reality TV star has three sons by three different men: Isaac came from her relationship with former beau Jo Rivera, Lincoln from her marriage to ex-husband Marroquin and baby Lux from baby daddy Chris Lopez.
As Radar has reported, Lowry has made noises about having a fourth child by sperm donor and freezing her eggs.
The mother of three boys also told followers on Saturday about choices she's made while on Teen Mom 2, "There's probably more but i wanted to clear those two things up. I have been feeling a lot of regret lately and i can say i haven't made some of the best choices over the last few months & Doing so on camera & then reliving them all over hasn't ever been easy."
Lowry added, "I regret allowing my emotions to take over with cast members. I regret getting sucked into filming about the drama involving people that truly don't have any effect on my every day life."
"I really want to focus on growing myself and my brand and work on eliminating all toxic people and situations from my life. So for anyone, fans & supporters included, that I've hurt or offended, I apologize."
"Sometimes i have to look at a situation & be honest with myself & i don't think I've handled things the right way lately. Soooo I'm starting over," Lowry declared via Twitter.
