Horrified by being pregnant

I had almost 5 nightmares tonight, all about me having a 3rd baby. I feed my child every 2 hours so every time i slept, i got another dream about a possible child and now am paranoid. A month and half ago, my husband and i had live sex one night. The rest of the days we religiously used condoms. Am on the pill but i forgot to take it a few times. Am still breastfeeding a lot and my period aint back yet. My mom told me i look pregnant, once when i was bloated. I crave noodles and meat. It is all i want. I dont even know if am writing to get advice or vent. Am just so tormented. Any tips on how to avoid pregnancy are highly appreciated.
